As a rule, more than one specification type is always required in customer projects. It has proven to be best practice to implement a superclass in the customer namespace to be able to add new logic across specification types or extend existing standard logic.

The superclass inherits from /SCT/QP_CL_VART.

In these instructions:

• Create package

• Create a general class for inheriting specific rule types

• Create a general interface for inheriting specific rule types

Create package

• Create super package (ZQP_VART)

Create object

• Create the class: ZCL_QP_VART

• Create interface and assign to class: ZIF_QP_VART
