• What is the cause and solution for SAP error message DMEE658 - Reference ID &1 was deleted from aggregation ?

  The SAP error message DMEE658 indicates that a reference ID was deleted from an aggregation in the Data Medium Exchange Engine (DMEE). This typically occurs when there is an issue with the configuration of the DMEE tree or when a reference ID that is expected to be present in the aggregation is missing or has been removed.
  Cause:
  
  Missing Reference ID: The reference ID that is being referenced in the aggregation is no longer available or has been deleted.
  Configuration Issues: There may be a misconfiguration in the DMEE tree structure, where the aggregation is expecting certain reference IDs that are not defined.

  Solution:
  
  Check DMEE Configuration: Review the DMEE tree configuration to ensure that all necessary reference IDs are defined and correctly linked in the aggregation.
  Restore Deleted Reference ID: If a reference ID was deleted unintentionally, consider restoring it or recreating it in the DMEE tree.

  Consult Documentation: Refer to SAP documentation or notes related to DMEE for any specific guidelines or updates that may address this issue.
