BDC execution failure in .NET RFC - returns subrc - 1001 -- URGENT HELP!!!!

Hi All,

We have created a simple BDC function module for tcode pr01 and this BDC has been enabled for remote.

The BDC works well when we execute from SAP GUI client. But when we execute this from .NET using SAP Connector, the BDC does not execute and subrc returns 1001.

The BDC take a export parameter which has to be updated in PR01 - bascially these are receipt amount.

We have been trying this for the past 2 weeks and for reason unknown the BDC is not working as expected.

Thanks a lot for your help
