is there a scenario where different po document types are maintained in one company code.
what are the document types available in MM other than NB?
In case if you want a different number range for a process then you have to define a different document type
Example if you want a seperate NR for subcontracting PO's then you have to create a new doc type.
Apart from NB we have
FO - Framework order
UB - Stock Transport Order
DB - Dummy PO( Most of the time this is not used)
Thanks & Regards,
