Dear J S,
Generally while making the operation level confirmation through CO11N we will do the GI /GR against operations for the production orders..
for this we have maintain the master data in the Routing..
In routing we can control the GI / GR against operation i.e. GI (261) movement components we will assign through the component allocation by maintain the back flush for the desired components
similarly GR(101) Movement we will control through Control Key(with Auto GR activation) which we will assign in the operation
now let me know where is your problem
Regards,
Venkatesh..
