PO For Outside Operation

[DSD]

Hi,
Can anyone through some light on following issue:
Whenever I run Order Procesing (R31410) it gives me PO NO for that Work Order & Corroesponding Outside Operation. But the problem if I rerun the same report (R31410) it gives me different PO No. Why it is so?

It will do this if you are re-attaching the Work Order Routing. You must use the Data Selection and WO Status conrol to make sure that you don't keep re-attaching the Routing. Check the first Processing Option Tab in the R31410 on the Version you intend on running on WO's with Routings already attached (& PO's generated). Switch off the functionality to attach the Routing or update it.
