Purchase Order Data Migration

[Former Member]

I am doing Data Migration for PO's. The senario is we are extracting PO's from the exisiting SAP system and loading into another. The question is can we assign an exterrnal PO number to the current PO number and then after loading change it back to internal number?

Idoc is not an option

Without doing any adjustment to number range, use the idoc method to create the PO and pass the source PO number in the idoc. PO will get created with the source PO number in the target SAP system as well.

Yes. You can. Create the external number range for purchasing document and assign it for your document type in external portion. (at that time you can remove the internal number if assigned any)

Then enter the PO number manually and create your all PO.

Then you can create internal number range for your purchasing document and assign it for your document type in internal portion.

Then do not enter any PO document number manually, leave it blank at the time of PO creation, system will use the internal number range. (if not required the external number range, you can remove it from document type)

Just remember Number range will be different for external and internal. You can't use only one number range as external and internal.
