RFC not working when called from BADI

Hi,

I am calling a R3 RFC FM (RV_INVOICE_DOCUMENT_READ) from CRM system to read the invoice details. I am retriving the condition records, Item details and partner details using this RFC call. This RFC FM is returning correct condition records when RFC call is made from stand alone program but it is not returning Condition records when call is made from BADI (the other entries like partner and Item details are coming perfectly in BADI also).

Please let me know if there any suggestions/solution.

Thanks,

Rajinikanth G
