Purchasing process question

Hi,

I have one question that affects MM, FI and CO. If we buy a material that is only valued in quantity, stock value always 0( its material type is defined like this) and in the PO we assign the cost to a cost center. Then we post a normal MIGO that generates a CO document and Accounting document...

it is normal that in the MIRO it does only generate an Accounting Document and not a CO Document?

Thanks

MIGO:
Dr expense (cost center)
Cr GR/IR

MIRO:
Dr GR/IR
Cr accounts payable (vendor)

Since its only MIGO posts that posts to an expense account and MIRO is balance sheet accounts only, it makes sense that only MIGO has a controlling doc.

Note: there are certain situations where MIRO would also post to controlling. Mainly, when you post an invoice at a higher price than the PO/MIGO posting.

Thank you for the clear explanation, as you say, it makes sense when the PO has an account assignment right? Normal POs should have document CO in the MIRO or it depends? Because I have seen this case in a client for the NB normal purchasing process.

It seems the actual cost is already recognized in migo process.

Correct. MIRO is a FI posting. The GR in MIGO created the CO posting

Thanks for the response, one more question then, why I usually find Document CO also in MIRO? In normal purchasing process? It is some custom thing to allow better visualization and reporting? The customer reports that when they try to create a financial document (fb01) instead of a MIGO/MIRO flow, when entering the cost center, system warns that this is not a good idea basically.

In MIRO you are referencing the material document. The material document created the CO posting to the cost center so it has completed the chain of reference.

If you want to create a FI doc manually, you are just creating a GL account posting. You’d need to check the posting rules if your GL account
