I intent to do an inventory marking for my new Purchase Order to my previous PO which already invoiced.
So in my item - transaction now after the new (or 2nd) PO created, I can see these two lines which is expected:
The 1st line is from the new PO and the 2nd line is from the previous PO which already invoiced.
In my 2nd PO, from the line, open line menu Inventory -> Marking :
But there is nothing for me to do the marking with :
The one listed is only the current LotId from the current PO.
How to do inventory marking ? so this 2nd PO relates each other with the 1st PO ?
Is there any rule / condition to make it available for marking ?
