Hi everyone,

We are facing a serious issue and would really appreciate any kind of help in this regard.

Couple of days ago, our Ax 2012 R3 application crashed while development on the DEV server and we did not have any back up of our latest changes. All we want is to somehow get the forms, tables and classes code from the Model DB.

Is there any way we can achieve this?

Please help us.....

Hi Ahsan,

When you say you want to retrieve the code from the application, what do you want to do with this code? Do you want to deploy the code to another environment for review or do you want to look at any specific code?

As for the error, it looks like you have added the field MTQDepartmentHierarchy twice in DIRPARTYTABLE. I suspect you added it to DirPartyTable and to one of the tables extended from DirPartyTable. You could try cleaning out SQLDictionary and see if you can open the AX application and then remove these conflicting fields from the tables. Try running the following command on your Dev environment AX database and check if that lets you start the application

DELETE FROM dbo.SQLDICTIONARY WHERE TABLEID = 2303 -- DirPartTable AND FIELDID = 86131

Thanks a lot for the help Gunjan

Can you tell me the process of retrieving the actual code from our customizations?

Will we do it through some cmd commands or there are some folders where the code is saved?

Hi Ahsan,

You can setup a new server, install AX 2012 R3 with the same CU (as the Dev server that crashed) and restore the model DB on this new server and retrieve the code changes. All the code changes are in the model DB, so recovering them shouldn't be an issue.

But, before you go ahead and spend time setting up the new server, did you look for logs to check why the application crashed?
