Dear Vellai,
It sounds personalization.
Take a look into this thread: https://scn.sap.com/thread/3537080
If it occurs on your frontend tools (tools that connect on your BW Abap) or on transaction RSRT, you have to review the DSO 0PERS_VAR
If it is java only, check the table RSPERS_VAR. There you should find a personalization of this user.
Delete the personalization with priogram RS_PERS_ACTIVATE
Let us know if persist.
Kind Regards,
Edward S. John
