User Description update

[whereisbrian44]

Dear all,

I try to change user description using BAPI BAPI_USER_CHANGE  or IDENTITY_MODIFY. I hope that will change IDADTYPE too (the same than using Fiori).

In both case function modules return a message 201(SUID01) : User attribute "Description" cannot be maintained in this system.

We have a CUA.

This description can be changed using Fiori Application but not in workbench system.

After trying to see this property in transaction SCUM, I am not able to see corresponding property.

Any idea?

Thanks for your help.

Regards,

David
