we have a requirement where temporary variables will be displayed based on the template we select.(temporary variables will be created under template in m2m table in the backend).
Now we have requirement where those variables needs input validation( those variables are not directly a catalog variables,i.e., it will be shown based on the template which is in another table)
I could like to know , how exactly the validation regex is validating the variable once it is applied to a catalog variable (which is ootb) Like to know the background logic or any ootb script which has the linking logic between validation regex and catalog variables in servicenow.
This might be helpful for us to have some similar idea for our requirement.
Thanks in advance!
