• What is the cause and solution for SAP error message WA790 - ------------Events with linkages that have errors ---------------------- ?

  The SAP error message:
  WA790 ------------Events with linkages that have errors ----------------------
  typically occurs in the context of SAP Event Management (SAP EM) or related modules where events are linked to each other, and some of these linkages have inconsistencies or errors.
  
  Cause
  
  The error indicates that there are events with linkages that contain errors.
  This usually means that the system has detected inconsistent or incorrect linkages between events.
  Possible causes include:
  
  Events linked to non-existing or deleted events.
  Linkages that violate business rules or data integrity constraints.
  Incomplete or incorrect event data causing linkage errors.
  Data inconsistencies due to manual changes or system errors.
  Issues during event creation or update where linkages were not properly maintained.
  
  
  
  
  Solution
  
  
  Analyze the Event Linkages:
  
  Use transaction codes related to Event Management, such as:
  
  /SAPTRX/EVM_EVENT (Event display)
  /SAPTRX/EVM_LINK (Event linkage display)
  
  
  Identify which events have linkage errors.
  
  
  
  Check Event Data Consistency:
  
  Verify that all linked events exist and are valid.
  Check for any missing or incorrect data in the event records.
  
  
  
  Correct or Delete Faulty Linkages:
  
  If linkages are incorrect, either correct the linkage or delete the faulty linkage.
  This can be done via standard SAP transactions or by using custom reports/tools if available.
  
  
  
  Reprocess or Recreate Events:
  
  If events are corrupted, consider reprocessing or recreating the events properly.
  
  
  
  Use SAP Notes and Support:
  
  Check for relevant SAP Notes that address known issues with event linkages.
  If the problem persists, raise a support ticket with SAP, providing details of the events and linkages.
