  The SAP error message CM_EHFND_LHR031 indicates that there is a duplication issue in the hierarchy records for a specific location. This error typically arises when the system detects that there are multiple entries for the same location under the same parent in the hierarchy structure, which violates the uniqueness constraint expected in hierarchical data.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are multiple records for the same location (identified by "&1") that are trying to be assigned to the same parent location (identified by "&2").
  Data Migration Issues: If data was migrated from another system or if there were manual entries made that were not properly validated, it could lead to duplicates.
  Incorrect Hierarchy Configuration: Misconfiguration in the hierarchy setup can also lead to this error, especially if the same location is inadvertently added multiple times.
  
  Solution:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to query the relevant tables (e.g., the hierarchy tables) to identify the duplicate entries for the specified location and parent.
  Remove Duplicates: Once identified, you can either delete the duplicate records or correct them to ensure that each location is uniquely assigned to its parent.
  Data Validation: Implement data validation checks to prevent duplicates from being created in the future. This can include setting up constraints or using validation rules during data entry.
  Review Hierarchy Configuration: Check the hierarchy configuration settings to ensure that they are set up correctly and that there are no logical errors in how locations are structured.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE16 (Data Browser), SE11 (Data Dictionary), and possibly SE78 (SAP Archive Link) to manage and view the hierarchy data.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on handling hierarchy records.
  Documentation: Review SAP documentation related to the specific module you are working with (e.g., SAP EHS, SAP Logistics) to understand how hierarchy management is supposed to function.
