How To Fix WA620 - Instance linkage between & & and & & cannot be deleted

SAP Error Message - Details

• Message type: E = Error

• Message class: WA - Messages from Workflow Event Manager

• Message number: 620

• Message text: Instance linkage between & & and & & cannot be deleted

What causes this issue?

The instance linkage between the tuple (object type, event) and the
tuple (receiver type, receiver ID) cannot be deleted.

System Response

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

How to fix this error?

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.

• What is the cause and solution for SAP error message WA620 - Instance linkage between & & and & & cannot be deleted ?

  The SAP error message:
  WA620: Instance linkage between & & and & & cannot be deleted
  
  Meaning / Cause
  This error occurs when you try to delete an instance linkage (a relationship or connection between two instances/objects) in SAP, but the system prevents the deletion because the linkage is still required or referenced elsewhere. The placeholders (& &) represent the involved instances or objects.
  Common causes include:
  
  The linkage is still active or in use by other processes or objects.
  Referential integrity constraints prevent deletion because dependent data exists.
  The linkage is part of a mandatory relationship that cannot be removed.
  The user does not have sufficient authorization to delete the linkage.
  The system is enforcing business rules that prohibit deletion of this linkage.
  
  
  Solution / How to Resolve
  
  
  Check Dependencies:
  
  Identify if the linkage is referenced by other objects or processes.
  Use transaction codes or tools to analyze dependencies (e.g., SE11 for table relationships, or specific application transactions).
  
  
  
  Verify Business Rules:
  
  Confirm if the linkage is mandatory or required by business logic.
  Consult functional documentation or SAP notes related to the module you are working in.
  
  
  
  Authorization Check:
  
  Ensure you have the necessary authorizations to delete the linkage.
  Check your user roles and permissions.
  
  
  
  Delete Dependent Objects First:
  
  If other objects depend on this linkage, delete or adjust them before deleting the linkage.
  
  
  
  Use Correct Transaction / Method:
  
  Use the appropriate SAP transaction or program designed to delete such linkages.
  Avoid manual deletion in tables unless explicitly recommended by SAP support.
  
  
  
  Check SAP Notes:
  
  Search for SAP Notes related to message WA620 for any known issues or patches.
  
  
  
  Contact SAP Support:
  
  If the issue persists and you cannot identify the cause, raise a support ticket with SAP, providing detailed information about the instances involved.
