Is it possible to auto-populate a DFF field value depending on the value selected?

Hi,

We'd like to set some DFFs in the Purchasing Order. We expect when we select 1 DFF the other one would be auto populated. Is it possible?

For example:

DFF1: It has 3 values- A,B,C

DFF2: It has 3 values- AA, BB, CC

When we select A in the DFF1. AA would populate automatically. If we select C, CC would pop.

Thanks,

Junjie
