3. Run the command “Get-NavappInfo” using the correct parameters.
4. If you did not find the symbols of “System”, “Test” and “Application” then publish the symbols first.
5. Inorder to publish the symbols of “System” and “Test” use the “Publish-Navapp” command with correct parameters. The app files are available under the installation folder under “Dynamics.365.BC.32615.NA.DVD\ModernDev\program files\Microsoft Dynamics NAV\140\AL Development Environment”.
6. Install both System and Test app from above path.
7. Now the remaining symbol is “Application”. Inorder to get this symbol published
Run the command prompt as administrator and path to “C:\Program Files (x86)\Microsoft Dynamics 365 Business Central\140\RoleTailored Client”
Then run the command of “finsql.exe Command=generatesymbolreference, Database=”DatabaseName”, ServerName=ServerName. This command takes some time. You can find the progress under “C:\Program Files (x86)\Microsoft Dynamics 365 Business Central\140\RoleTailored Client\NavCommandResult.txt” file.
If that notepad file says it is succeeded, then run the command of “finsql.exe generateSymbolReference=yes”.
