PPDPIM :Update IDP: ITS Programming

Hi all,

I am trying to update employees IDP ( PPDPIM ), through ESS. For this I have developed a RFC function module and written ITS program in SE80 which call the function module from ESS.The function module updates the IDP thru a BDC call transaction.

When I test the function module in R3,it creates records correctly but it is giving error ( 1001 ) when i test it from ESS.

need help in this regard.
