Problem using BAPI_PO_CREATE1 w/ reference to a PR

Hello Gurus,

I'm having problems using the BAPI BAPI_PO_CREATE1 w/ reference to a <b>PR</b>. When I run the BAPI I encountered an error msg: <i><b>Delivery date is in the past</b></i>. The PO was created but the delivery date in its schedule lines appears to be blank.

How do I go about it?

Thanks,

Jeffrey
