It is not possible to create or modify SAP accounts with the following name in SAP:
The names are "hardcoded" and protect the One IM user from locking himself out of his SAP - system (e.g. deletion of all users due to an operator error).
If such users are to be changed or non-existent ones created, this must always be done in the SAP GUI itself.
This list should be added to the documentation.
Related error messages should be adjusted.
This is a product defect (35695).
