Work Center lock error for incorrect plant combination

[Former Member]

Hi,

We have work center MECHANIC defined for three different plants A, B and C. We created a work order wherein planning plant is A and main work center used is MECHANIC with plant combination B. Now for some reasons business decided not to use work center MECHANIC for Plant A and blocked the work center MECHANIC for plant A in transaction IR02. After blocking the work center, now if I go to work order and save it, I am getting an error message that Work Center MECHANIC is blocked for Plant B whereas actually work center is blocked for Plant A. I have checked the master data for work order (floc and equipment), operation work center as well as main work center. No where in the work order combination of work center MECHANIC with plant A exists. If I double click on error, it doesn't bring any detail screen so I am not able to see any message no. here. Being functional I have not done any debugging on this. Any pointers on this issue will be helpful.

Thanks!
