How to restrict variables to allow only English characters on GE/IGO form in Legal Service Delivery?

[ShwetaD]

Hi Team,

As per my story requirement, we need to allow only English characters in variables on the GE/IGO form in Legal Service Delivery.

Currently, the form is allowing other language characters as well. I would like to know:

What is the recommended approach to restrict variables to accept only English characters?

Should this be handled using a Client Script, UI Policy, or Regex validation?

Is there any out-of-the-box configuration available for language restriction?

Please suggest the best practice approach.

Thanks.

Hi @ShwetaD 

No, there is no simple checkbox for "English Only," but there is an OOTB feature called "Variable Validation Regex" that is designed exactly for this. Regex Validation is the Best Practice.

Step 1: Create the Validation Rule

1. Navigate to Service Catalog > Catalog Variables > Variable Validation Regex.

2. Click New.

3. Name: English Characters Only (ASCII)

4. Regular Expression:

   ^[ -~]*$

   5. Validation Message: Please enter English characters only.

• Click Submit.

Step 2: Apply to your Variable

1. Open your Record Producer or Catalog Item (GE/IGO Form).

2. Open the specific Variable you want to restrict (e.g., short_description or u_details).

3. Go to the Type Specifications tab.

4. In the Validation Regex field, select the "English Characters Only" record you just created.

5. Update the variable.
