Renaming Variable Labels and Variable Names

[Abdul333]

Hello All,

We have requirement to unify Variables Names and Questions. But those Variables having Ui policies, Ui policy actions and Client scripts and reference qualifiers in Catalog Items.

What should be procedure to unify all the variables with one Name for all catalog items so that the functionality remains same.

If possible please share a template to unify the variables without disturbing the old functionality or please provide the best practice to do this. How to replace the renamed Variable name in existed catalog ui policies, ui policy actions and catalog client scripts.

Thanks,

Abdul

HI @Abdul333 ,
I trust you are doing great.

1. Identify the variables that need to be unified across all catalog items. Make a list of the old variable names and the desired new unified name.

2. Create a backup of the existing catalog items, including their UI policies, UI policy actions, and client scripts. This is important in case you need to revert any changes.

3. Update the variable names and questions in the catalog items to the unified name. This can be done manually in the ServiceNow platform's catalog item configuration.

4. Once the variables are updated, you'll need to update any references to the old variable names in UI policies, UI policy actions, and client scripts.

   • For UI policies and UI policy actions, you can use the ServiceNow platform's scripting capabilities to update the references. Write a script to search for the old variable name and replace it with the new unified name. Here's an example script:

var grUIPolicy = new GlideRecord('sys_ui_policy');
grUIPolicy.addQuery('variable', 'old_variable_name');
grUIPolicy.query();

while (grUIPolicy.next()) {
    grUIPolicy.variable = 'new_unified_name';
    grUIPolicy.update();
}

For client scripts, you can use a similar approach to search and replace the old variable name with the new unified name. Here's an example using Javascript:

var grClientScript = new GlideRecord('sys_script_client');
grClientScript.addQuery('script', 'LIKE', 'old_variable_name');
grClientScript.query();

while (grClientScript.next()) {
    grClientScript.script = grClientScript.script.replace('old_variable_name', 'new_unified_name');
    grClientScript.update();
}

1. Once you have updated the references in UI policies, UI policy actions, and client scripts, thoroughly test the catalog items to ensure that the functionality remains intact. Make sure to test various scenarios and use cases to validate the changes.

Hi @Amit Gujarathi , Thank you so much for your response.

we have around 250 variables with different names. for that we need to run it for 250 times with new and old variable names?
