Issue/Introduction

When copying certain projects in MUX, we get the following error:

Copy Failed - CMN-0007: 'PROJECT' attribute 'obj_request_category' is required

What can be the cause?

Log file shows the following error:

Environment

Any Clarity release

Cause

The Project Category attribute at the project object is set as required and the projects erroring at the copy action do not have the field populated

Resolution

If the Project Category attribute is set as required, please ensure it is populated at project level, so copying the procect instance is successful
