ALM_MEREP_010_GETLIST rises an exception

The function module ALM_MEREP_010_GETLIST (BAPI Wrapper of MAM_010 SyncBO) rises an exception because of missing mandatory parameter in a call statement:

CALL FUNCTION 'ALM_ME_NOTIFICATION_GETLIST'
       EXPORTING
*         I_PARTN_ROLE      =
           i_partner         = ls_user_data-partner
           i_work_cntr       = ls_user_data-work_cntr
           i_plangroup       = ls_user_data-plangroup
           i_sel_variant     = ls_notification_profile-profile_sel_not
      TABLES
           notification_list  = notification_list
*           notification_list1 = notification_list1
           return             = return.

The mandatory parameter I_INVENTORY_PROF has been missing. I haven't found a note about this situation.

Does somebody have more information about this problem (System: R3=46C , PI=2004_1_46C patch 0006)?
