I created Internal order and set its status as REL on Jan.
I changed its status as TECO on Feb.
I didn't post WIP on Jan.
I run result analysis KKA1 with "Period:Jan" on Feb.
But it didn't post WIP.
Instead, it posts Cost of Sales.
So, it seems the Result Analysis doesn't care about past status
of Internal Order, even though I set past period on selection screen.
It cares only current status.
Am I correct? Or is this customizing issue?
