QUESTION: 129 Exam Topic: Develop and Test Code (Testlet 1)

DRAG DROP (Drag and Drop is not supported)
A company uses Dynamics 365 Finance.
You create a new extension for a standard table.
You need to add a new method in the extension.

Which five actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

See Explanation section for answer.

Answer(s): A

Explanation:

Step 1: Create a new project in Visual Studio.

Step 2: Add a new class to the Visual Studio project with the _Extension suffix.
You first create a new class in the extension model.
This class will augment the table, and enable access to the table's fields and methods in a manner that is easy to read and understand. It's important that you choose the correct name for your augmentation class.

Step 3: Set the class as final.

There are a few rules for augmentation classes:

They must be final.
They must be suffixed by _Extension.
They must be decorated with the [ExtensionOf()] attribute.

Step 4: Decorate the class with the [ExtensionOf(tableStr(TableName))] attribute.

Example:
[ExtensionOf(tableStr(InventTable))]
final class InventTableMy_Extension
{
public void myDefaultInventLocationId()
{
// This would have partner specific logic to initialize the new field.
this.MyInventLocationId = this.inventLocationId();
}
}

Step 5: Add a new method to the class and implement it.
You can now add new methods to the augmentation class. These methods will then appear in IntelliSense for variables of the InventTable type, just as if they were defined directly on the table. This behavior applies to both static methods and instance methods.

NOTE: Each correct selection is worth one point.
Hot Area:

See Explanation section for answer.

Answer(s): A

Explanation:

Box 1: SID1234
Parameters
All methods have their own scope. A method can take one or more parameters. Within the scope of the method, these parameters are treated as local variables and are initialized with a value from the parameter in the method call. All parameters are passed by value, which means that you can't change the value of the original variable. You can change only the local variable in the method. This local variable is a copy of the original variable.
Box 2: 5
