Change the status of the field

Hi experts,

I've created a template role in PFCG, and I left the org. level information blank in template role.

However, one of the authorization field of plant, I accidently keyed in one of the plant codes. When I generate the derived roles, that authorization field of plant is also filled with the code I entered in derived roles.

I tried to get in template role to remove the plant code, and leave it blank as "unmaint. org. level", but the field status has been changed into "field changed", and no plant code is copied in derived role when I re-generate both template and derived roles.

How can I change the status of that field like the other org. level fields, and make the field info filled by the org. level info in derived roles?

Thanks in advance,

Regards,

Junior
