Table USRM0 updated

Hello All,

On the ECC6 version, when executing transaction VD03, on the first screen, there is a push button named 'CIN Details' but not always displayed. Some users see it and some do not. This depends on the user id which is stored in the table USRM0. Does anybody know how this table USRM0 is updated. Please help!

Your input is greatly appreciated!!!

Thanks and best regards,
