Contact Person General Data Fields in Relationsip not editable-S/4 Hana BP

Hi All,

Issue is the fields in Contact person general data are greyed out. Can anyone please let me know the solution to make these fields editable.

1. Create Person with Role "Contact Person"

2. Create New BP and Assign the Contact person created in step1 under "Relationship" "Has Contact Person"

3. Fields like Function, Department, VIP, Address etc., are greyed out in edit mode.
