It looks you haven't described your issue and it just states "MC error must be 0" which does not seem complete. Iād like to recommend to bring more details and context to your initial inquiry.
It also helps to have screenshot(s) to better understand what you are trying to do in your process.
This will increase your chances to receive meaningful help from other Community members.
You can configure Windchill to ensure the objects collected in your promotion request are "error free". However, we do not use this feature because there may be many exceptions. I am no WC admin, therefore I am not able to help you on this š
Contact your Windchill administrator to discuss why you are forced to use modelcheck.
He should explain what is controlled in your models and tell you what you should correct.
Or you can convince him to turn off MCERROR check during checkin
If the error is presented during promotion request, then it is some customization that controls your models if the modelchekc was used and MCERROR is really 0.
Also in this situation you should contact your Windchill / CAD Administrator to discus what is wrong.
Each organization has different rules and different quality check.
If you need to solve the issue without your administrator, you need to open the objects in CAD software and run the modelcheck and all errors has to be solved in the model.
After the model contains 0 MC ERRORS the promotion request can be completed.
