Enable AL and C/AL side by side for NAV Upgraded Database to Business Central

Now that NAV 2017 Database is upgraded to Business Central v14 (Refer link), it's time to connect your AL Development with your Business Central environment.
One of the issues with this approach is that NAV Database does not have the symbols generated.

- VS Code & AL Language Extension

- finsql.exe

- Business Central On-Premise with Windows Client

Demonstration:

1. Connect VS Code to Business Central Database:
- Ensure that in Business Central Administration > Development > Enable Development Service Endpoint and Enable Debugging and Enable loading application symbol references at startup.

Enable Development in Business Central Administration

- Ensure that the launch.json file in your project corresponds to your Business Central On-Premise Server

2. Check if Symbols are present in the Database:
After running the Get-NAVAppInfo -ServerInstance <ServerInstanceName> -SymbolsOnly, I realized that the symbols are missing.

To generate the symbol reference run the command finsql.exe Command=generatesymbolreference, Database="<Database Name>", ServerName=<ServerInsstanceName>

Go to C:\Program Files\Microsoft Dynamics 365 Business Central\140\Service, run CMD Prompt as Administrator and paste the above command

This didn't generate the symbols.

To install the System App and Test App as a part of symbols, go to the Product DVD and search for *.app in Folder

Now you can use Publish-NAVApp to upload extensions to Business Central

Now, upon running Get-NAVAppInfo

Hence, its now time to refer to my old blog Tenant default is not accessible

So, now that only the Application(BaseApp) App is yet to be installed, the steps are as follows.
- Export TXT Objects into a single folder. Exception: Codeunit ID should not be >= 2000000001

- Run Generate Symbols:
"Microsoft.Dynamics.Nav.SymbolReferenceGenerator.exe" "C:\Users\cfadmin\Desktop\TXT" "C:\Users\cfadmin\Desktop\App.app" Application 14.0.29530.0

Now the App file is generated, you need to publish using Publish-NAVApp and check with Get-NavAppInfo

Now Restart the Server Instance and download symbols from VS Code.

and upon installation of the extension, the Business Central Environment shows the successful deployment of the extension.

This blog focused on the area where you can migrate your customization with the upgraded database.
Also, the data can be migrated into respected tables using OnInstall and OnUpgrade triggers in AL Development.

Hopefully, this blog helps in installing your AL Language Customization to BC Upgraded Database.
