The error message itgenibz022 indicates that the client ID used is not valid.
This is also reflected by the error itgenscr562 where ionBiz reports that the ionBiz-credentials (client ID and/or client secret) are invalid.
It is recommended to validate the client ID and client secret and try again.
Also it is quite uncommon that there are multiple data containers on ionBiz within the same database. Please check whether this is the intended design.
It has been fixed. The error occurred due to a change in the rights of our admin user. I’ve added a resource to the resource field with the correct rights.
