5) Delete the new customized field and customized table with sync schema validation .

6) Now to check , run the upgrade sales header table .it will show you all data.

  • Do the same for customized table.

7) Create extension in visual studio for the customized field and customized table with same id of field and name.

  • And Create a codeunit with subtype -> install

8) Publish this app in Microsoft Dynamics NAV 2018 using ISe.

  • Open ISE :


Import-Module ‘C:\Program Files\Microsoft Dynamics NAV\110\Service\NavAdminTool.ps1’

Publish-NAVApp -ServerInstance Dynamicsnav110 -SkipVerification

Path : C:\Users\njain\Documents\AL\ExtensionV2Project\Default publisher_ExtensionV2Project_1.0.0.0.app.Install from Client.

Error while downloading symbols or unable to access customized table in Visual studio code

Get-NAVAppInfo -ServerInstance DynamicsNAV130 -SymbolsOnly

You should be getting an output as this

If you are getting the version for 11.0 or any other versions in than please follow the below steps.

Open Powershell with Admin

  • Import-Module ‘C:\Program Files\Microsoft Dynamics 365 Business Central\130\Service\NavAdminTool.ps1’

Later Please place the files System.app and Test.app in a folder of your choice.

The files are located in the dvd in the following folder (Use the version of BC)

X:\DVD\ModernDev\program files\Microsoft Dynamics NAV\130\AL Development Environment

Run the below 2 commands in the same Powershell (Change instance and path accordingly)

  • Publish-NAVApp -ServerInstance DynamicsNAV130 -PackageType SymbolsOnly -Path C:\Test\System.app -SkipVerification

Publish-NAVApp -ServerInstance DynamicsNAV130 -PackageType SymbolsOnly -Path C:\Test\Test.app -SkipVerification

The finsql.exe command must be executed client side.

Run a command prompt and change directory to the client folder (typically C:\Program Files (x86)\Microsoft Dynamics 365 Business Central\130\RoleTailored Client).

From the client directory run the following command

finsql.exe Command=generatesymbolreference, Database=”Demo Database NAV (11-0)”, ServerName=localhost\ITMBSNAV

where Database is the database where you wish to generate symbols and ServerName is the SQL Server instance where the Database is attached

NOTE: The command itself might give the idea to be completed in few milliseconds but this is not true since finsql.exe continue to run in background even if the prompt returns to the command console window.

Use Task Manager to inspect the resource consumption by finsql.exe process.

When running finsql.exe with the generate symbol reference parameter key within command prompt, it might seem the process ending too fast or that nothing happened.

Just close the command prompt and run Task Manager (taskmgr.exe) and go to tab Details to inspect finsql.exe background process and its resource consumption.

You might notice memory growing up high of several hundreds of MB and process disappear when finished.

After this please try to download the symbols again.
