How do I bring in purchase orders from non-Lawson to Lawson?

You can import purchase orders from an outside source into Lawson's Purchase Order application by running a batch program. Purchase Order Interface from Non Lawson (PO520) interfaces all the records that are needed to process purchase orders.

Purchase Order Interface from Non Lawson (PO520) allows you to correct a few records and re-run the program to process only the records that were changed. For example, there are 500 records that are available and you only wanted to process 20. You could add a run group to those records and run Purchase Order Interface from Non Lawson (PO520) for that group.

When the import process is complete, you correct any interface errors by using Purchase Order Interface (PO53.1).
