Change of work center in prod order in not confirmed operations in APO / ECC
I am awaiting my sap access but face already some questions that I am not sure of whether or not it is possible to change a work center in production order in operations that are not confirmed yet.
e.g. operations 10-20 are confirmed,
operations 30 has not started yet: can I change the work center in this and further operations?
thanks for helpful input!
