3798123 - Error G00056 when saving task group in Define Task Group - SD1 last task S1180 cannot have successor tasks

When creating or saving a task group in configuration activity Define Task Group (104737), the system raises error G00056:

"Task group SD1: The last task S1180 cannot have successor tasks"

The long text may identify task S1010 as a successor task. The following warnings may also be displayed:

"Task group SD1 cannot contain both data tasks and consolidation tasks"

The error can prevent a newly created customer task group from being saved even when the new task group itself is not SD1.

Additionally, when opening Define Reclassification Tasks, the message "Fill out all required entry fields" may occur if mandatory fields such as Short Text are missing for existing reclassification tasks.
