The values are not changing in the RITM or Catalog task variable type

[rahul16]

I have category and subcategory in the service portal it's working fine subcategory values change based on the category but when I want to change the values in the RITM form or SC task it's not working

And also I see when I select the category and save the form and then I see the subcategory new values based on category how to overcome this problem?

I created a UI policy to make the fields edit on the request item form

Did you use onChange() catalog client script for this?

If so, then make sure that Applies on Requested Items and Applies on Catalog Tasks checkboxes are checked/true.

Add this in the Variable attributes of subcategory.

ref_qual_elements=category.

How have you configured the dependency between those 2 variables?

is it based on sys_choice? or is it based on script?
