The methodExistenceCheck cannot be implemented generally for the interface Check existence. You must therefore implement this method for each of your object types. In the implementation, you scan the database fields concerned and check whether the object identified by the key fields actually exists.
The interface Check existence is always supported if the
Exceptions for the method
The exception Object does not exist is defined for the methodExistenceCheck under the number 0001 in the interface Check existence. You must implement this exception at the appropriate point in the program. Use the following macro instruction:
EXIT_RETURN 0001 SPACE SPACE SPACE SPACE.
Other methods (for example, the methodFind ) call the method ExistenceCheck in their implementations. Every object type should support this interface (and therefore this method).
Position the cursor on the entry with a blue background that has the component name Interfaces, and choose . EnterIFEXIST in the input field.
