Table Extension 中实现display方法

This posts helps you to understand and create a "display"  method for the table extension.

Lets say, the requirement is to add a method in the standard table, it can be achieved either by creating a table extension.

So in this scenario we had a requirement to add a display method in the standard table "CustTrans".

In Dynamics 365 we wont be able to add the new method or modify the existing method to the standard table or to an extension table.
