Dear Kamal
Thanks for your reply
I tried to say that once the production Order has been settl, we get a total sum from all concepts = 0
but, this zero comes from a cost element used to set variance, I mean deviation are balanced via this element.
So, we need to use a way to set this cost element to zero also but via manual, due to all the posting were don in wrong way.
PLease ease let me know if I got to be clear.
