You as a Key User, restricted the Write Access for a particular user for creating Supplier from Business Partner Data work center. But still that user is able to create Supplier from Supplier Base and Payables work center.
Reproducing the Issue
In Application User and Management, for work centers BPM_SUPPLIERS, BPM_SUPPLIERSCENTRAL and BPM_SUPPLIERSFIN, No access is given for Write access.
In principle, a New Supplier can be created in four different work centers:
- Work center view Supplier in Work center Business Partner Data
- Work center view Supplier in Work center Supplier Base
- Work center view Supplier in Work center Payables
- Work center view Business Partner in Work center Business Partner Data (for create as scenario)
If an user has all these views (what will not happen very often) and you want to restrict the user not being able to create suppliers, you have to restrict all the four work center views . If you forget to restrict one of them you will see this by the way as well in the "business user authorizations conflict UI".
The system work as designed.
