BBP_PD_PO_CREATE PO creation

Hi Experts,

     i am creating a tool in SRM system to create puchase order locally by passing header and item data through a file. i am using this function module BBP_PD_PO_CREATE.

But while using this, i am prompted with a remote login to FI system (not required in my scenario).

Please let me know if this is the correct function module or not , if not, please share which FM to use.

Regards,

Tashi
