Hi,

We want to activate the person assignment DFF: PER_ASG_DF. This will contain a segment with a Yes/No choice list attached.

We currently have a person DFF segment, person level, with similar value (Yes/No).

The requirement si to populate the new person assignment DFF segment with the existing value in the person DFF segment.

Can you please suggest how we can achieve this?

Thank you.
