How Can I restrict DFF values based on Expense report Template other than Context field

Hi ,

Need help in restricting Global Data element based on Expense Report Template .

Requirement :

1. I have two expense Report Templates and defining DFF for "Expense Report Line" by selecting Global Data Element  Context.

Say 1st Template Name is G&A Template

2nd Template Name is COS Template

2. In Global Data Element Context . I have given 1 segment Billable and the values for this is Yes or No.

Now I want to restrict this values like below :

If I select G&A Template , my value in Billable Segment should always  shows "NO" only

If I select COS Template , my value in Billable Segment should always  shows  either YES or NO .
