Retrun to approval route

I nedd that when in a purchase order occurs a change, automatically return to approval route. is it possible? Can anybody give me an idea?
Thanks

Jorge,
There are processing options on the Purchase Order Entry program (P4311) for change order processing. Using that setup, you can have a PO return for approvals after a change has been made.

Thanks Jane
That mean a new PO?

No, it will not be a new PO. You'll still have the same PO # and type, but there is a change order number (PHCORD) on the PO header (file F4301). It starts at 0 for the original PO and will increase by 1 with every time the PO is changed.

Hope this helps.
Janet
