How to make a read only field editable in MDG UI

Hello Experts,

There is a MDG specific boolean field- REFLEXIVE (Same Partner) in the entity BP_VENFCN (Partner ) on UI. It is by default ready only once a Partner Function code is entered.

I want the field "Same Partner" to remain editable on UI once a Partner Function code is entered, and allow a user to check or uncheck.

If anyone knows please comment.

Note: I am using SAP MDG 7.0; Data Object: Supplier

Thanks,
