Missing stock during Process Order creation
I'm facing a new problem here in my client.
Thats the situation:
We are trying to generate a subcontracting process order to delivery a semi finished material to a supplier in order to be packed. We already have a contract with this ssupplier, its been saved as a supplier, we already did this operation with him more than once.
The question is that during the process to create the process order, system is giving us a message that there is no enough stock off semi finished material to be send to the supplier. (it comes a message that is missing a small quantity to fiill the right amout we want to send to the 3rd party - something around 1,5% of the total amount)
But if we go to MMBE we can see the same amount of stock we want to delivery to the supplier in free utilization.
Besides we are using here WM we didn't see any difference that could give us the error.
In QM inspection batch all the amount were released (321 movement) no sample quantity was taking/retained.
The most insteresting part is the we did the same operation for the next batch of the same semi-finished material. I mean for the batch produced yesterday (monday may 9th) we already sent to the 3rd party for packing but for the batch from last friday, we are facing the issue.
In this case we have the same kind of process order, same 3rd party, same materials, same process a so on.
Please could you give me an idea where should I look for a solution.
Thanks in advance.
