Hello,
Production order operations, are having labor hours maintained against activity type and cost center maintained in the work center and standard hours maintained in the routing.
During order operation confirmation actual labor hours are entered by the workers.
Also we have a 40 hour work week, and workers also fill in their time sheets, using CAT2 against the same labor work center and the production order.
This creates double booking of labor hours.
How can this be avoided ? Is it possible that hours booked by the labor in CO11N are somehow transferred and displayed in CAT2 against the day they were booked ?
Current work around we have is to not enter labor hours while confirming using CO11N.
What is the best possible way to handle this 
Any inputs by experts would be highly appreciated.
Best Regards,
Ameya B.
