• What is the cause and solution for SAP error message WE015 - Enter target key different to source key ?

  Certainly! Here's a detailed explanation of the SAP error message WE015 - Enter target key different to source key:
  
  Error Message
  WE015 - Enter target key different to source key
  
  Cause
  This error occurs during the processing of IDocs (Intermediate Documents) in SAP, specifically when you are trying to assign or map a target partner key that is identical to the source partner key in the partner profile or during partner determination.
  
  The system expects the target partner key (used for outbound processing or partner mapping) to be different from the source partner key (used for inbound processing or original sender).
  If both keys are the same, it can cause confusion or conflicts in partner determination or message processing, hence the system throws this error.
  
  
  When does it occur?
  
  During partner profile configuration (transaction WE20).
  When setting up partner profiles for inbound/outbound IDoc processing.
  When defining partner functions or partner mappings.
  When manually editing or creating partner keys in the partner profiles.
  
  
  Solution
  
  Ensure that the target partner key is different from the source partner key.
  Review the partner profile in transaction WE20:
  
  Check the partner type and partner number for both source and target.
  If you are mapping or assigning a target partner key, make sure it is not the same as the source partner key.
  
  
  If you intended to use the same partner key for both source and target, reconsider the design or mapping logic because SAP requires them to be distinct for proper processing.
  If you are unsure about the correct target partner key, consult your business process or integration design to identify the correct partner number.
  
  
  Additional Information
  
  Partner keys are identifiers used in IDoc processing to distinguish between different business partners (customers, vendors, etc.).
  The source key usually represents the sender or original partner.
  The target key represents the receiver or mapped partner in the outbound process.
  This distinction is important for routing, message processing, and partner determination.
  The error helps prevent configuration mistakes that could lead to incorrect message routing or processing loops.
