We have a req as below- can you suggest the best approach

a) Po Number coming from external system has alpha numberic number range and copy of the PO should be created in SAP with the same alpha numeric number.

b) If we maintain the alpha numeric ranges in our system, should we also create a new doc type for the same? Can we use the existing Doc types(NB/UB) or should we create new doc types? We prefer to keep the same doc type.

You get the PO from the external system probably with an Idoc, isn't it?

To my experience (with other Idocs) is SAP usually posting with the number that is provided in the IDoc, only if the number is empty then it makes use of the number range to assign the next number.

Why would you create a new document type, each document type can have 1 internal and 1 external number range.

If your external number is in conflict with an existing external number range then you need a new document type, if you have not existing external number range then just set it up and assign it to the existing document type.

Yes Jurgen we get the external PO in an IDoc.

So are you telling that there is no need to maintain an external alpha numeric number range in this case as the PO will be created automtically?The requirement is to keep the same PO number between SAP and external system.
