The possible recipients of a work item are all those persons, holders
of positions, jobs or organizational units who are linked to the task
represented by the work item at runtime.
No possible recipients could be determined for the work item involved
here. Either no relationships were defined for the task or a read error
occurred when the database was read.
The task ID is listed in the technical data of the work item.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
