Hi all,

Very interesting topic it is. 

With Dynamics AX 2012, some new BP errors have been introduced. Often, while fixing BP errors, I turn to the List of Best Practice Error and Warning Messages page on MSDN for help.

But what if you are getting a BP error and there is no clear description on how to fix it. In such scenarios, I always debug the BP error and try to see what is causing this BP error in the first place.

This guy explained it very well, please follow the below link. please  click on the below link or copy and paste in URL to read it in details.
