Authorization Profiles for Working with the AWB 
As an administrator, you will need special authorizations in the Business Information Warehouse and in the source system, which you can determine in the user settings.
You need the following authorization profiles for the administrator’s tasks:
S_RS_ALL (Business Information Warehouse: All authorizations)
S_RS_BW20A1 (all additional authorizations needed in the Business Information Warehouse 2.0A)
S_IDOC_ALL (All authorizations for IDoc functions)
B_ALE_ALL (All authorizations for ALE/EDI authorization objects)
S_A.CUSTOMIZ (Customizing [for all activities with system setting])
The ALE user also requires two further authorization profiles - for further information see
Authorization Profiles for Background Users.
