I have a requirement to store SAP user name in several languages. And as far as I have noticed SAP can do this, because in table ADRP there's a field NATION, which is a key field. My problem is that I can't find a standard way to enter user name translation into SAP. Neither I see this possibility in transaction SU1, nor in SU01 etc.
Can someone advise standard transaction or report to manage SAP user name translations?
Thanks a lot in advance for your help.
