FI numbering acording to vendor
I would gladly welcome help for the following problem:
I need to generate FI documents with a numbering according to the vendor.
I tried to do so in snum, with field subobject data element equal to lifnr.
But SAP does not allow this as the data element has more than 6 characters.
Does anyone has any suggestions on the best way to overcome this?
Thank you kindly.
