Hi Eric,
Please take a look of this thread:
Analyzing Costs on Production Order
This is what Akhil Baluja said:
In your case, the target quantity is double from Plan quantity might be because of in Routing of the material the Base quantity used for calculation of Standard Cost might be double & after the cost estimate has been released it was reduced to correct figure Or the Alternate routing was used while calculating standard Cost & in actual production.
Please check....
Check if this could be your problem.
Kind Regards,
Mariano
