I try to set routing with External processing.
I have 2 questions.
I would really appreciate you, if you could answer my questions.
I still have not understood the relationship between "Control key" and "Purchase Order"
The routing is like below
10 self manufacturing
20 External Processing with the control key is pp02
30 self manufacturing
In case I set "+" (Externally processed operation) for "External Processing" in "pp02", the Purchase Requisition will be created.
However in case I set "X" (Internally processed operation / Externally processed operation) for "External Processing" in "pp02", the Purchase Requisition will not be created.
My question is in case I set "X" for "External Processing" for Control key, how can I create Purchase Requisition?
Should I create Purchase Requisition manually?
In case I set task 20 as External Processing.
What kind of Work center should I regist for task20?
Is it dummy work center or is empty OK?
