Did you know that the CRM entity "object type" code changes for different environments in QA and development. I didn't know that but Gaurav posted this question to the community to see if there was a way by which we can sync up these object types in development and QA.
Unfortunately, there is NO straight way to keep them in sync! However, you can use the metadata webservice to retrieve the correct objecttypeid for a particular entity. Check CRM SDK or let me know if you need the code. Thanks - Dipesh
