• What is the cause and solution for SAP error message USMD1B202 - Predecessor node &1/&2 does not have parent node &3/&4 ?

  The SAP error message USMD1B202 indicates that there is an issue with the hierarchy of nodes in a master data structure, specifically in the context of SAP Master Data Governance (MDG). The error message states that the predecessor node (identified by &1/&2) does not have the expected parent node (identified by &3/&4). This typically occurs when there is a mismatch in the hierarchical relationships defined in the master data.
  Cause:
  
  Hierarchy Structure Issues: The predecessor node is expected to be a child of the specified parent node, but it is not correctly linked in the hierarchy.
  Data Inconsistencies: There may be inconsistencies in the data being processed, such as missing or incorrect parent-child relationships.
  Incorrect Data Entry: During data entry or migration, the relationships between nodes may not have been established correctly.
  Configuration Issues: There may be issues with the configuration of the master data governance settings that define how nodes are related.
  
  Solution:
  
  
  Check Hierarchy Structure: Review the hierarchy structure in the relevant master data area to ensure that the predecessor node is correctly linked to the parent node. You can do this by navigating to the relevant master data transaction and checking the relationships.
  
  
  Correct Data Relationships: If you find that the predecessor node is not correctly linked to the parent node, you will need to correct the relationships. This may involve:
  
  Adding the predecessor node as a child of the correct parent node.
  Deleting incorrect relationships if they exist.
  
  
  
  Data Validation: Validate the data being processed to ensure that all required relationships are present and correctly defined. This may involve running data validation reports or using tools provided by SAP MDG.
  
  
  Review Configuration: If the issue persists, review the configuration settings in SAP MDG to ensure that the hierarchy settings are correctly defined. This may involve checking the data model and the configuration of the relevant business rules.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing hierarchies in the context of your specific master data governance scenario.
