2 voucher related to same voucher source

Hi, 

I would say “under certain conditions”, this is normal. 

MPCCOM Accounting is the identifier created when a transaction is created. It essentially links the accounting id to the transaction ID.   Transaction id being the inventory transaction, labor transaction or similar.  Generally - you always get accounting effects from a given operational transaction. Exceptions to this exist, that’s a different topic.  

OK - to continue with why 2 different vouchers.    This can happen when the accounting value changes after the transaction “and” after the transaction was transferred., or example assume the original transaction was a PO arrival and the part is set as weighted average with invoice consideration being set as transaction based.   The PO arrival created a cost transaction.  Assume that transaction was transferred. Later or next month the invoice is processed with a different cost.  IFS will then go back and revalue the original posting. But because the original transaction was already transferred, we create new posting lines tied to a new voucher (assuming another transfer). 

IMO - nothing to solve.  I guess you could delay the transfer until after all the additional cost are reported, but that would cause many other issues. I don’t believe you should delay the transfers.  

In short, it is normal, under some conditions, to have two voucher numbers for the same MPCCOM accounting ID.
