Change an existing purchase order via Purchasing ® Purchase order ® Change. Make the necessary changes and save the PO.

The new message is compared with the last successfully transmitted message. PO change notices indicate whether any new items have been added to the PO, and/or whether any already transmitted items have been changed.

When the message is transmitted, only those changes that are simultaneously new and print-relevant are included. The system sets the change indicator for the new message. To check the change indicator, choose Header ® Messages in the PO item overview.
