General BAPI Question

[Former Member]

In several of the "Create" type BAPIs that I've looked at, the BAPI requires you provide the document number as a field in the input parameters.

Take for example BAPI_PO_CREATE1 requires a PO_NUMBER. How would an external system know what the next PO_NUMBER would be? Even if some lookup was provided, another PO could be created before this BAPI was called.

Hi,

You would only need to populate this if you had an external number range defined. If you are using internal number ranges then the system will allocate it and you do not need to pass anything.

you need to pass it only in case of external number ranges, and even there, We follw the practice of assigning the different set of ranges to different systems ( if the same txn can be called from more than 1 partners ); so that even for the external numbering those should not conflict with the different systems or users using the same #s in SAP

if you can search the forum or google about number ranges.. it will give you a better picture..
