Hi
I guess this will not work.
You have operation cost assignment switched on.
This will create for each operation one PR item with a certain Account assignment.(the respective operation )
When converting the PR into one PO you are able to collect all the PR´s in one PO and than the SES will go against each operation.
So the only thing which you have to take care is that all the PR´s are collected into one PO.
PM WO does not create one PR item with multiple account assignment.
Whe you do not create the PR/PO out of the PM order you get the capability to use multiple account assignment but not when you start from the PM Order
I hope this clarifies the situation
thanks
Stephan
