Gross good receipt VS net invoice receipt

[former_member673852]

Dears,

In a standard SAP passive process I need to manage the purchasing of a gross quantity, which must be managed in the stock, but its invoice sent by the vendor will be referred to the net quantity. I try to better explain with an example:

- PO item 100 kg

- GR 100 kg --> only after the good receipt the logistic department is able to confirm to the vendor the real net quantity to be invoiced (hypothesis is 90 kg)

- receive IR 90 kg.

In this situation the invoice cannot be posted in the system, because the financial office do not match the quantity between the GR and the IR.

Our idea of solution is to cancel GR and change the quantity in the PO item with 90 kg, than post a 101 movement for 90 kg and another material document of 10 kg with movement type 501 referred to a cost center.

After that the invoice will be posted for 90 kg.

This solution it is not good due to the many canceling material documents that must be created and about the different accounting side related to the cost center moved by the 501 movement type, instead of stock accounting of the 101 .

Could you please suggest me another kind of solution that could be applied in this scenario ?

Thank you very much in advance.
