• What is the cause and solution for SAP error message /BOBF/CONF130 - 'Key is equal to parent key' flag is mandatory for node &1 ?

  The SAP error message /BOBF/CONF130 'Key is equal to parent key' flag is mandatory for node &1 typically occurs in the context of Business Object Processing Framework (BOPF) when there is an issue with the configuration of a node in a BOPF business object. This error indicates that a key field in a child node is being set to the same value as its parent key, which is not allowed unless explicitly configured.
  Cause:
  
  Key Configuration: The child node is configured in such a way that it requires a unique key that should not be the same as the parent key. This is often a design decision to maintain data integrity and ensure that child records can be uniquely identified.
  Data Input: The data being processed may inadvertently be setting the child key to the same value as the parent key, which violates the business logic defined in the BOPF configuration.
  
  Solution:
  
  
  Check BOPF Configuration: 
  
  Go to the BOPF configuration for the business object in question.
  Verify the settings for the child node. Ensure that the "Key is equal to parent key" flag is set correctly based on your business requirements.
  If the child node should allow the same key as the parent, you may need to adjust the configuration to allow this.
  
  
  
  Adjust Data Input:
  
  Review the data being passed to the BOPF business object. Ensure that the child key is being set correctly and is not unintentionally being assigned the same value as the parent key.
  If necessary, modify the logic in your application or data processing layer to ensure that the keys are set appropriately.
  
  
  
  Consult Documentation: 
  
  Refer to SAP documentation or the BOPF framework documentation for more details on configuring keys and relationships between nodes.
  
  
  
  Testing: 
  
  After making changes, test the business object to ensure that the error no longer occurs and that the data integrity is maintained.
  
  
  
  Related Information:

  Node Configuration: In BOPF, nodes represent entities and their relationships. Each node can have its own key configuration, which defines how it relates to parent nodes.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on BOPF configuration.
  
  If the issue persists after checking the configuration and data input, consider reaching out to SAP support or consulting with a technical expert familiar with BOPF and your specific implementation.
