RE: Data management in D365

Hi Vignesh,

After creating data entity have you run synchronization?

If not, please run DB synchronization once.

Thanks!

Data entities creates a View in SQL server. Check in SQL server database whether the view is available over there or not. If it is not available in SQL server database then synchronization is not happening properly.

Hi Nishant,

I can see the View it is available in SQL but when i tried to sync the project in Visual studio i'm getting an error

"Infolog diagnostic message: Infolog diagnostic message: 'Cannot create record for data entity - WasteCodeTable. The most common cause is if the entity metadata is not compiled. Recompile and retry database sync.' on category 'Error'."

The message itself is depicting that your metadata is not build properly. Rebuild your Solution to check are there any errors and on successful rebuild Synchronize once again. I can understand it's frustrating and taking too much of your time, but there is no other go to deal with the problem. :)
