MIRO - planned delivery costs - how to change invoice party

Dear all,

This is my scenario: I receive one invoice for planned delivery costs from vendor A. This invoice refers to PO's 1, 2 and 3.

PO's 1 and 2 were created correctly and the freight vendor was correctly filled in planned delivery costs condition (vendor A). But PO 3 has the wrong freight vendor.

I cannot post the invoice because when chosing PO's 1, 2 and 3 in MIRO, I am forced to choose between the correct vendor (of PO's 1 and 2) and the wrong vendor (PO 3).

Is there any way to solve this? I know I can change the freight vendor in MIRO for planned delivery costs but I believe this is only applicable if I have one invoice for every delivery.

Am I correct?

Your help would be worth millions.

Thanks in advance. Joã
