Hi Junaid,

The reply from Judy is related to a fixed bug in Dynamics 365. As you are using AX 2012, this mentioned issue is not your resolution. Anyway, it can be a similar bug. You can search on LCS issue search for possible known issues and hotfixes. Have you also tried installing the latest available service updates?

Hi Andre,

I just updated my AX2012 from cu9 to c13 with my old Data Base and performed successful build and sync.

Hi Junaid,

There are a lot of changes. What exactly was updated when you talk about updated AX2012 and old Database? Was a correct CIL created using the compilation and build process? Did you synchronize the database?
