When programming batch jobs you might encounter the following error message log from a failed to execute batch job:
System.InvalidCastException: Unable to cast object of type ‘<class name>’ to type ‘Dynamics.Ax.Application.Batchable’.
The cause of the problem is typically because the CIL has not been compiled for the batch job you are running. Since batch jobs only run in CIL it is important to ensure the CIL compile is complete before trying to run your batch jobs. This can be from a partial build for a full build, but it must be a clean build to ensure batch jobs will work correctly.
