• What is the cause and solution for SAP error message /STTPEC/WHS_MSG031 - Only one parent is allowed within one aggregation/dis-aggregation. ?

  The SAP error message /STTPEC/WHS_MSG031 indicates that there is an issue with the structure of your aggregation or disaggregation process in the SAP system, specifically in the context of the Supply Chain Management (SCM) or Warehouse Management (WM) modules. This error typically arises when there is an attempt to define multiple parent nodes within a single aggregation or disaggregation operation, which is not allowed.
  Cause:
  
  Multiple Parent Nodes: The primary cause of this error is that the system has detected more than one parent node in the aggregation or disaggregation hierarchy. In SAP, each aggregation or disaggregation process can only have one parent node to maintain a clear and logical structure.
  Incorrect Configuration: There may be a misconfiguration in the master data or in the settings related to the aggregation/disaggregation process.
  Data Integrity Issues: There could be issues with the data integrity, such as duplicate entries or incorrect relationships between nodes.
  
  Solution:
  
  Review the Hierarchy: Check the aggregation or disaggregation hierarchy to ensure that there is only one parent node defined. You can do this by navigating to the relevant configuration settings in SAP and reviewing the structure.
  Adjust the Configuration: If you find multiple parent nodes, you will need to adjust the configuration to ensure that only one parent node is present. This may involve reassigning child nodes to the correct parent or restructuring the hierarchy.
  Data Cleanup: If the issue is due to data integrity, perform a cleanup of the relevant master data to remove any duplicates or incorrect relationships.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on configuring aggregation and disaggregation processes in your version of SAP.
  Testing: After making the necessary changes, test the aggregation/disaggregation process again to ensure that the error has been resolved.
