You modelled a Keytest user on a business user ABC (ABC represents the user name). You notice that the keytest user has a different view/ access to ABC.
SAP Cloud for Customer
You changed the user ABCs Access Rights after the Keytest user was created. For example: a change of Sales Organization assignment, or a change to the access rights, etc.
The keytest user's assignment is a snapshot of the impersonated user at the time of assignment. Changes done to ABC will not be reflected for the Keytest user.
You need to re-impersonate the business user by Keytest user again from scratch.
