  2. Add the following global variable:

    Type

    Subtype

    Customer

    Customer

    TempCustomer

    Record

    Customer

  3. View the properties of the TempCustomer variable.

  4. Set the following property:

    Property

    Value

    Temporary

  5. Close the Properties window.

  6. Add the following code to the OnRun trigger of the codeunit:

    MESSAGE('Customer Count: %1\TempCustomer Count: %2', Customer.COUNT, TempCustomer.COUNT);
    
  7. Save and close the codeunit.

  8. When you run the codeunit you will see a window like the one shown in the following screenshot:
