Variable editors display variable values in fulfiller forms. A requester specifies these variable values in the catalog item questions. The VEditor is applicable only for the ordered catalog items. This editor is a formatter added on requested items and catalog tasks of an ordered catalog item.

This editor displays the values of questions specified while ordering the catalog item. By default, the VEditor is applicable for requested items and catalog tasks.

You cannot use it for any other table. The default variable editor is applicable only for record producers. This editor is a formatter added on records that are generated by a record producer for task-extended tables.

This editor displays the values of questions specified in the record producer. By default, this editor is applicable for the Incident, Problem, and Change tables.

For other tables, configure this editor. It is not applicable in Service Portal and not recommended for catalog forms, and should only be used in requested item, target record, and catalog tasks. After you configure the default variable editor for a task-extended table, you can view and edit the values of questions specified by the requester in the record producer. Applicable only for records generated by a record producer. Types of variable editors based on the catalog item type: For a catalog item, the VEditor displays the values of questions in the requested item and catalog task forms.

For a record producer, the default variable editor displays the values of questions for records generated from a record producer for task-extended tables. VEditor The VEditor is applicable only for the ordered catalog items. To support a catalog UI policy or a catalog client script on the VEditor for requested items and catalog tasks, select the Applies on Requested Items and Applies on Catalog Tasks check boxes for the catalog UI policy or the catalog client script.

Note: You can make the Variable Editor Readonly scripts conditional by adding conditions to them. Figure 1. Catalog UI policies, catalog client scripts, catalog data lookups, reference qualifiers, and dependent reference fields are supported on the default variable editor only for task-extended tables.

To support a catalog UI policy or a catalog client script on this editor, select the Applies on the Target Record check box for the catalog UI policy or the catalog client script.

Figure 2. Default variable editor. The following variable types are not displayed in the variable editor.Administrators and catalog administrators often define multiple catalog items that use the same group of service catalog variables.

Catalog managers and catalog editors can attach a variable set for items and categories to which they are assigned. However, catalog managers and catalog editors cannot create a variable set. For example, a catalog administrator defines 10 catalog items for types of servers.

The request process for all these items asks the same five questions, using the same variables. Associating these variables individually per catalog item is repetitive, time-consuming, and error-prone. Also, to make a single change to multiple catalog items involves manually changing each item. For example, to add a variable to 10 catalog items, you would need to manually associate the variable with each item. Variable sets allow you to create a collection of structured variables that can be reused across multiple catalog items and order guides.

Using variable sets saves time because you do not have to create the same variables individually for many catalog items. Also, when variables should be modified, you can modify the variable set and the changes are reflected across all the catalog items that are associated with the variable set. Variable sets also allow you to define catalog client scripts and UI policies that are applicable to the variables in the set. A catalog administrator can provide read, write, and update roles to access a variable set.

When you access variables of a variable set, a validation is first done at the variable set level, and then at the variable level. If the access is blocked at the variable set level, then the access settings on the variable are over-ridden.

If the access is allowed at the variable set level, then access at the variable level is verified. Use a single-row variable set to capture data from variables that are grouped together, while submitting a catalog item request for a single entity.

Use a multi-row variable set to capture variable data in a grid layout while submitting a catalog item request for a group of entities. For example, for HR during the reorganization of employees, a single record producer should be able to capture the relevant information such as the department and manager for a group of employees.

Also, when you request a catalog item to order virtual machines and servers, configuration options should be captured as a single request. In this case, a requester can define multiple hardware units as rows and their configuration options as columns of a multi-row variable set. You cannot set Global as True for any variable that belongs to a multi-row variable set. So, a multi-row variable set is not available in catalog tasks.

You cannot select variables of a multi-row variable set when defining the following for a catalog item:. Create a set of variables and add them to multiple catalog items and order guides for reuse. Variable sets can have one of many layouts.

You can define the order of the variables for each item.

Some variables define, describe, or compose the pieces of the workflow such as workflow activities. Some variables are available specifically to facilitate the execution of a workflow such as scratchpad variables.

Some variables define, describe, or compose the data records being manipulated by the workflow process for example, the elements of a Glide Record that are defined in a dictionary. Activity variables are properties specifically associated with a workflow activity. These are the inputs that appear on the activity definition when a specific activity is dragged onto the workflow canvas.

These variables are properties that define, compose or describe the workflow activity, or the work it is designed to perform. Activity variables are declared in a related list within the Workflow Activity Definition. Workflow variables are external values that are passed into and referenced by a workflow during its execution.

Reload a Form or Related list from a Client Script

Workflow variables are declared in a form available from the Workflow Editor gear menu. Note the Column name field. Use this value when accessing the variable from a script. Workflow variables do not appear on the workflow canvas, they are only available for view from the Workflow Activity menu. After being declared in a workflow, values can be assigned to the variables from where the workflow is kicked off.

If a workflow that accepts inputs is called from within another workflow, those input values can be set from the workflow canvas within the UI of the workflow activity.

Each input variable declared for a subflow will have a text box input area displayed on the activity. Within these text boxes, the variables can be set with any value either from the scratchpad or from within the current record. For more information, see Workflows used as subflows. Store and share string-based variables as name-value pairs between workflow activities.

The scratchpad is global to the instance of the running workflow and as such, is available equally to all activities. Current is the database GlideRecord that kicked off the workflow, either by association to the table in the Workflow properties table or by being associated with a catalog item. Variables in current are the columns that are defined in the dictionary.

There is no way at runtime to add variables to the current record. Variables of a current record are displayed on the Glide Forms and Lists throughout the applications that use them. About this task. Note: If defining a new activity variable that is dependent on another activity variable, put the prefix "vars. For example, if the child field is dependent on a field named parentput the value vars. To access the variables or assign values to these variables within the workflow activity, use the vars variable of the workflow activity.

Workflow variables can be declared externally in a script and passed into a main workflow or they can be declared within a main workflow and passed as inputs to a subflow. To understand the use of these variables see Workflow catalog variables. The input variables are available to use in scripts. Declaration The scratchpad itself is automatically available to an executing workflow and requires no specific declaration.I recently came across another forum posting where the poster wanted to do something similar.

The difference for the most recent poster was that the variables were to be shown on an Incident form which had been generated by a record producer. There were some subtle differences in the way variables were presented on the different forms that made my original script unusable for the incident form.

These solutions can be used in a variety of places, but will most often be applied to the Catalog Item, Catalog Task, Incident, or Change Request tables. Its probably best to avoid writing any script at all if you can to lock down access to variables.

Service-now allows you to add roles to any variable in the system for this purpose. If you want to lock down variables without using a script, the solution can be found here. It also requires you to set access to each and every variable in the system individually. Probably the simplest way of locking down variables on a standard form via script is to create a business rule that checks to see if the variables have changed and then to abort the submission of the task record if they have changed.

If the user changes variable values and tries to submit the record they would get an alert telling them that they are not allowed to change variables. The other option is to simply not show the variables at all and instead dump them into the work notes or comments fields. Service-now actually provides a simple way to make a variable on a standard task form read only via client scripting. If you just need to disable one or two variables on a single item then this is probably the best scripting option.

The solution is documented here. More often than not however, if you are disabling variables at all, you are disabling them entirely or disabling them for a certain group of users. For that case, you could use a script like this one to lock down all of the variables on a form. It is designed to work on any task table in Service-now.

Could I use a similar script? You might be able to use what I have written as a basis, but I would guess that they would end up being pretty different. Checking each variable to see if it has a value would probably be pretty complicated due to all of the different variable types. My guess is that if I were to try and write a script for that it would probably have to be a pretty big hack to account for everything.

There is a way now! Thanks Mark. Is there any way to get the script to use the variable order from the catalog item to order the variables when writing using your script?

Thank you for the client script that makes the variables read only on the Request Item form. I have noticed that if you have a date variable filled in and you make an update to the form i. I assume that it has something to do with the removal of the calendar icons, but I am not positive.

If you could elaborate a workaround for this issue that would be greatly appreciated. The only workaround I can recommend is to use one of the other methods provided in the article.

Making a field read-only with a client script should not make that field lose its value upon save…regardless of the script used.The inputs into this workflow are essentially question:answer pairings that, when associated with a specific catalog task, become options on the task form. These options are generated by that catalog task activity within a workflow.

You can define variables as global or catalog item-specific. When a variable is associated to a catalog item and the workflow generating the catalog task is associated to the catalog item, the variable scope determines which variables are available for mapping within the catalog task activity in a workflow. You can declare requested item catalog variables at the catalog item level or at a global level. Also see, Global variable declaration option 2.

The catalog variables that appear are available to any catalog task that is initiated from within a workflow. These variables are only available to the catalog item referenced in the Cat Item field on the variable record.

You can declare a catalog item-specific variable directly from a catalog item record. Creating a catalog variable in this way automatically sets the Cat Item reference to the catalog item selected.

Catalog specific item variables are visible in several places depending on where in the process the variable is viewed. Declaration can happen and variables can be seen from within the menu, inside both the Maintain Items module and in the Item Variable modules of the Service Catalog.

Within a workflow, the Catalog Specific Item variables are available to the Catalog Task activity in the form of a slushbucket at the bottom of the Catalog Task activity. Item variables that are selected, are the question and answer pairs that will appear on the task that is generated by that instance of Catalog Task when executing that workflow. If a workflow is associated with a specific catalog item, the association acts as a filter for item variables that appear in the slushbucket of the Catalog Task activity.

The last place the variables are seen is in the task form that is generated by the Catalog Task Item. The variables selected in the slushbucket are the question and answer pairs that appear to the user on the task form. The Catalog Item Variables are available and assigned to a specific Catalog Task activity thereby to a specific task using the slushbucket entry of a catalog task. About this task. You can declare global catalog variables using the Service Catalog. The list of variables that appears in the workspace has a default filter of Cat Item!

Also see, Global variable declaration option 1. You can declare a catalog item-specific variable. Note the list of variables that appears in the workspace has a default filter of Cat Item! Selecting a Cat Item restricts the scope and availability of the catalog variable to that specific catalog item. Also see, Catalog item specific variable declaration option 2. Note the Variables related list. All variables declared using this related list have a Cat Item reference value of the current catalog item.

Variable names should not include white space and cannot begin with a number.So, you can thank Jacob Kimball for the brilliance of this solution. Here is how you could set up the business rule. The script is designed to hide any empty variables for any task records whether they are generated from a record producer or as a catalog item.

The client script is pretty simple since the heavy lifting is being done in the business rule.

That is Very Cool. This functionality should be a user configurable property setting in Service Now. One thing to watch out for are any fields that are still marked as mandatory, if the fields get hidden by the client script, the record may not be able to be modified. I would love to be able to extend this sort of functionality to email notifications.

Specifically approval requests. Currently all variables show up in those notifications. It would be nice to not include those that are empty. This is certainly possible, but it depends on how you are including those variable values in your email.

Hiding Empty Variables in the Variable Editor

You would have to add or modify a mail script for that notification to check each variable as it gets added to the notification and make sure that it has a value. Great example. Thanks for sharing! They are still appearing although the visibility has been set to false during the form-filling process.

Regarding hiding variables with a matching default value, you can modify the script to do this, but I think it will be difficult to determine which items to really hide.

You may have some cases where an un-changed default value might actually be useful information. Works find for one column layouts. Seems to be something with the setDisplay function. Thanks so much, this saved me so much time!

My only remaining issue is hiding the variable set title if all variables are hidden.
