Submit 'xxx' Exporting List to Memory returns no records for Extractor

Hi Gurus,

I have created an extractor that remotely calls a report and retrieves data into SAP BW

When I'm testing the extractor in RSA3 it works perfectly fine however, when called from SAP BW it retrieves no data.

The reason is that in the extractor I'm calling the report in ERP the following way:

DATA: BEGIN OF list_tab OCCURS 0.

INCLUDE STRUCTURE abaplist.

END OF list_tab.

SUBMIT zmrmm_xx WITH SELECTION-TABLE rspar_tab WITH p_nozero = p_nozero

EXPORTING LIST TO MEMORY

AND RETURN.

It turned out that this statement works fine when testing it in RSA3 however when called remotely the table LIST_TAB is empty.

Do you guys have any idea what may be the reason and how to overcome it?

I supposed it must be some memory management-related issue.

Any suggestion will be appreciated!

Thanks,

Maciej
