Extend a User-Created Table

Introduction:
Microsoft Dynamics Business Central allows extending Pre-defined Tables, which is basically Customization and it is achieved using Extensions. Using Extensions developers can modify Pre-defined Tables according to requirements. But the extension of a Table can be done only if its “Extensible” property is set as True. This property is by default set as True for Tables.
Now suppose a developer wants to extend a table that is created.

Pre-requisites:

• VS Code
• AL Language Extension
• Microsoft Dynamics Business Central

Solution:


Step 1:

Set the Extensible property of the Table that is supposed to be extended as shown below:
In this case, the table to be extended is “Properties”.

Step 2:

Now go to Extension Management and get the AppID, Publisher, Name of App and Version as shown below:

 

App Details

Put the above details of App in the dependencies section of the new extension where the table is to be extended as shown below and download symbols:

Step 3:

You can see that the “Properties” table is now available for extension. Here I have added a field “Extended Name” in the Properties Table. Also, that field can now be seen by accessing Properties Table by URL.
