Was verursacht dieses Problem?

The instance linkages for the specified receiver cannot be deleted.

Systemantwort

The action was terminated.
The entries in the instance linkage table are not changed.

Wie behebe ich diesen Fehler?

To minimize the size of the instance linkage table, the entries in the
table are deleted as soon as possible. This means deletion is attempted
at different times:
After the event (the last event for which this linkage is required) has
been received.
When deleting the receiver with the specified ID.
If the receiver is set to a status in which it can no longer receive
any events (for work items these are, for example, the statuses
<ZH>waiting</>, <ZH>error</>, <ZH>logically deleted</> and
<ZH>completed</>).
This error message may therefore have been triggered because the
relevant linkage had already been deleted beforehand (e.g. if a work
item is deleted which was already in the status <ZH>completed</>).
As it is generally attempted in the case of work items to delete a
possible instance linkage when a transition to one of the statuses
listed above occurs, this error message can also appear even if the
work item was never entered in an instance linkage.
However, this cannot be checked at the time when the (possible) error
is found.
If you receive this error and do not know whether the work item was
used in an instance linkage table, check existing entries in the
instance linkage table (for example using transaction
<DS:TRAN.SWEINST>SWEINST</>). If there are no longer any entries for
the specified tuple pair, you can ignore the error message. Otherwise
contact you workflow system administrator so that the instance linkages
which were not deleted can be removed.
