Error: Not authorised

Hi,

I am trying to get the document master data using the bapi BAPI_DOCUMENT_GETLIST2. When I execute this through se37, i am getting 11 entries. However, when i try to access the data from XI with the same BAPI and same user, its giving me the following error:

You are not authorized for with document type DRW

Is there any other role i have to assign to the user with which i am accessing?

Thanks,

Venkat
