Issue with BBP_INB_DELIVERY_CREATE

Hi,

I am trying to create inbound delivery for all open line items of the PO (manually using VL31N) using function module 'BBP_INB_DELIVERY_CREATE', i am passing only 2 fields (Delivery date & PO number) as i am passing the same to VL31N. I am not getting either error message or its creating Delivery.

I hope i am using correct function module to create Inbound delivery with ref to PO. Could you suggest me any thing on this?

Thanks

Satya
