• What is the cause and solution for SAP error message /SAPAPO/DP_EVENT150 - Event catalog &1 cannot be its own parent ?

  The SAP error message /SAPAPO/DP_EVENT150 indicates that there is an issue with the event catalog in the SAP Advanced Planning and Optimization (APO) module, specifically in the Demand Planning (DP) area. The message states that an event catalog cannot be its own parent, which typically means that there is a circular reference or a self-referential relationship in the event catalog hierarchy.
  Cause:
  
  Circular Reference: The event catalog is trying to reference itself as a parent, which is not allowed. This can happen if the hierarchy of events is incorrectly defined.
  Incorrect Configuration: There may be a misconfiguration in the event catalog setup, where the parent-child relationships are not properly established.
  Data Integrity Issues: There could be issues with the data integrity in the event catalog, such as duplicate entries or incorrect relationships.
  
  Solution:
  
  
  Check Event Catalog Hierarchy:
  
  Go to the event catalog in the SAP APO system and review the hierarchy of events.
  Ensure that no event is set as its own parent. Each event should have a valid parent that is not itself.
  
  
  
  Correct Parent-Child Relationships:
  
  If you find any events that are incorrectly set, modify their parent-child relationships to ensure that they point to valid parent events.
  
  
  
  Data Validation:
  
  Run data validation checks to identify any inconsistencies or errors in the event catalog.
  Use transaction codes like /SAPAPO/DP_EVENT to manage and maintain the event catalog.
  
  
  
  Recreate the Event Catalog:
  
  If the issue persists and cannot be resolved through adjustments, consider recreating the event catalog from scratch, ensuring that the relationships are correctly defined from the beginning.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to event catalogs in APO for any specific guidelines or known issues.
