• What is the cause and solution for SAP error message MMPUR_POHANDLER_TECH012 - External link &1 &2 &3 &4 already exists. ?

  The SAP error message MMPUR_POHANDLER_TECH012 indicates that there is an attempt to create or modify a purchase order (PO) or related document, but the system has detected that an external link (such as a reference to a document or an external system) already exists for the specified identifiers. This can occur in various scenarios, such as when integrating with external systems or when handling purchase orders that reference external documents.
  Cause:
  
  
  Duplicate External Link: The error typically arises when there is an attempt to create a new external link that already exists in the system. This could be due to:
  
  A previous transaction that created the link.
  An integration process that is trying to create a link that has already been established.
  Data inconsistencies or errors in the external system that are being reflected in SAP.
  
  
  
  Data Integrity Issues: There may be issues with the data being sent from an external system, leading to duplicate entries.
  
  
  Configuration Issues: Incorrect configuration in the integration settings or in the handling of external links can also lead to this error.
  
  
  Solution:
  
  
  Check Existing Links: Investigate the existing external links in the system. You can do this by:
  
  Using transaction codes like ME23N (Display Purchase Order) to view the purchase order and check for existing external links.
  Querying the relevant tables (e.g., EKKO, EKPO) to see if the external link already exists.
  
  
  
  Modify the Existing Link: If the external link already exists and is valid, consider modifying the existing link instead of creating a new one.
  
  
  Data Validation: Ensure that the data being sent from external systems is validated to prevent duplicates. This may involve checking for existing records before attempting to create new ones.
  
  
  Integration Configuration: Review the integration settings and configurations to ensure that they are set up correctly to handle external links without causing duplicates.
