• What is the cause and solution for SAP error message USMDZ3328 - &3 appears too many times in hierarchy &4 ?

  The SAP error message USMDZ3328 indicates that a specific node in a hierarchy appears too many times. This typically occurs in the context of Master Data Governance (MDG) when you are trying to create or modify a hierarchy structure, and the system detects that a node is duplicated beyond the allowed limit.
  Cause:
  
  Duplicate Nodes: The error is primarily caused by having the same node (or element) appearing multiple times in the hierarchy structure. This can happen due to incorrect data entry or a flaw in the data import process.
  Hierarchy Constraints: SAP has built-in constraints on how many times a node can appear in a hierarchy to maintain data integrity and avoid circular references.
  
  Solution:
  
  Check Hierarchy Structure: Review the hierarchy structure you are trying to create or modify. Ensure that each node is unique and does not appear more times than allowed.
  Remove Duplicates: If you find duplicate nodes, remove the excess instances to comply with the hierarchy rules.
  Data Validation: Implement data validation checks before submitting the hierarchy to ensure that duplicates are caught early in the process.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on hierarchy structures and constraints related to your version of SAP MDG.
  Debugging: If the issue persists, consider debugging the process or checking logs to identify where the duplicates are being introduced.
