When viewing a Grantee record the text Vendor (Read Only) appears next to the ID and the profile cannot be edited even by users with security rights. This only occurs for one record.
1. Go to the AP module and find the Vendor record for the grantee profile. 2. On the Vendor tab check the checkbox for Grantee and save. 3. Go back to Profiles and now see that the profile can be edited.
