There are activity types that have not been processed in step 2 Preparation. This can be verified by checking for activity types with the status “Still Open” in the same step.

The parameters maintained for the Preparation step should be reviewed to identify if any filters are defined that exclude activity types.

Specifically, check whether the option “Process selected Materials / no Activities” is enabled. If this option is selected, the system processes only materials, and no activity types are included in processing.

Make sure all activities are considered in preparation parameters, close tab 'Process selected Materials / no Activities' if it's openned,
then choose 'Process Again' and save the parameter, rerun preparation and settlement step, the error message should be gone.
