I installed a new MS Dynamics AX Instance with a new (Database, Application files, AOS…)
then i installed the SP1 Update then the SU3 Update, I compiled the application files and do step by step the initialization checklist and its all good!
we always do the customization in a local Instance(Updated SP1 and CU3) then moving them by the standard Import tool.
it maybe happened twice when i do a cycle any where it gives me a class error, i tried to select some of classes in the AOT and compile them, i figured that some of these classes got so many errors. its so weird since we are installing new Instances with the same steps and we got no errors.
I checked the Kernel version it is 5.0.1500.1313
Application Version 5.0.1500.1313
It means that i have the SU3 Hot-fix as i know. Im so sure that i compiled the whole application after i installed the Updates and i tried to compile it again (Initialization checklist tool) and the same problem is there (SO MANY ERRORS IN CLASSES)
Its weird because i installed so Instances before with a customization too and it didn’t happened!! Wondering what is the problem …
