Return Table empty in Web Service response

Hi All,

My Question is more of related to Web Service. I have created a Web Service from ABAP for BAPI_PO_GETDETAIL. This BAPI is working fine in R/3.

I am using this particular Web Service in Adobe Form (using only ADOBE LIVECYCLE Designer). It's is working fine If i pass the correct Data(Purchase order no.) I'll get the O/p. In case I put a wrong PO number I am not getting the values in return Table in response. (If i test the BAPI in R/3 i m getting a message in Return table that PO no. doesn't exist)

Any Help will be appreciated.

PS; I m using Adobe liveCycle designer 7.1 and Acrobat Professional 9.

Regards,

Sachin
