Table extension to add a field

Table extensions provide a way to add fields to a table without over-layering.
This means that we don't need to perform a code merge when the base package is changed.

We will add a field to the " SalesConfirmHeaderTmp " table, which we will use in the How to customize a document layout without an over-layer recipe.

To add a field to a table as an extension, follow these steps:
  1. Run Visual Studio and create your project.
  2. Locate the " SalesConfirmHeaderTmp " table in the Application Explorer as shown in the screen shot below.

  3. Right-click on it and choose Create extension.
    Note: Please make sure that your project model should be correct.
    In the screenshot below my project model is " Fleet Management " which is incorrect.
    " Fleet Management " is not a extension model of " Application Suite " model that is why the " Create extension " is non clickable.



  4. Right-click on your project and go to " Properties "

  5. Property window will appear then select your appropriate model as shown in the below screen shot
    Note: " AXGuru_Customization " is my custom model which i created as an extension of " Application-Suite " Model
    For create a custom model visit this link click here


  6. Follow the step 3 again and you will see that " Create Extension " option is clickable



  7. Click on " Create Extension ".
  8. " SalesConfirmHeaderTmp.Extension " Table is added in your project,
    now right click on it and click " Open "

  9. Right click on the " Fields " note,
    Click " New " then select the type ( example : String, Integer,Real etc )

  10. In my case i am adding the " String " type field.
    and set it's properties.
    Name : Axg_Description
    EDT : Description
