Conditionally Making a DFF Field Mandatory Based on Charge Account Segment in RSSP

Hello Team,

We have a business requirement to make the ‘ASMB Location’ DFF mandatory only when the GL string begins with 01-20 (Company 01 and Business Unit 20) while creating Purchase Requisition in RSSP. To support this requirement, we created the ‘ASMB Location’ DFF at the requisition line level and used Advanced Expressions to conditionally display it. However, the logic is not working as expected.

For your reference, please find the screenshots below -

We are unsure if the conditions used in the expression are correct. Any guidance or suggestions would be greatly appreciated. For information, we are using 25D version.

Thank you.
