• What is the cause and solution for SAP error message DMC_GENERAL012 - Parent and child sender node mapped as DEFAULT to same receipient node ?

  The SAP error message DMC_GENERAL012 indicates that there is a mapping issue in the Data Migration Cockpit (DMC) where both a parent and child sender node are mapped to the same recipient node as "DEFAULT." This typically occurs in scenarios involving data migration where hierarchical relationships between data entities are defined.
  Cause:
  
  Mapping Configuration: The error arises when the mapping configuration for the data migration process is set up incorrectly. Specifically, both the parent and child nodes are trying to map to the same recipient node, which can lead to ambiguity in data processing.
  Hierarchical Structure: In a hierarchical data structure, each parent-child relationship should be uniquely defined. If both nodes are mapped to the same recipient without proper differentiation, it can cause conflicts during data migration.
  
  Solution:
  
  
  Review Mapping Configuration:
  
  Go to the Data Migration Cockpit and review the mapping settings for the relevant data objects.
  Ensure that the parent and child nodes are mapped to different recipient nodes if they are intended to represent different entities.
  
  
  
  Adjust Mapping:
  
  If the parent and child nodes should indeed map to the same recipient, consider using a different mapping strategy that allows for this without causing conflicts.
  You may need to create a more specific mapping that distinguishes between the parent and child nodes.
  
  
  
  Test the Changes:
  
  After making adjustments to the mapping, run a test migration to ensure that the error is resolved and that data is being processed correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or guides related to the Data Migration Cockpit for best practices on mapping configurations and hierarchical data structures.
  
  
  
  Seek Support:
  
  If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide insights based on your specific configuration and requirements.
