• Message type: E = Error

• Message class: STC_TM - Task List Manager Messages

• Message number: 319

• Message text: Class &1 is not a valid task list configuration class

What causes this issue?

Configuration classes for task lists need to be derived from base class
CL_STC_SCENARIO_CONFIG.
Provided class &V1& is either not derived from the base class or
contains syntax errors.

System Response

The task list is using the default configuration.

How to fix this error?

Check the task list if the configuration class is needed anymore: Remove
the class from the task list using transaction <EX>STC01</> if it is not
required anymore.
Check the implementation of the class: The class should inherit from
CL_STC_SCENARIO_CONFIG and it should be syntax error free.
