  The SAP error message /S4PPM/MIGR_DPR051 indicates that a Work Breakdown Structure (WBS) element has been persisted twice as a right element under its parent. This typically occurs during data migration or when importing project data into the SAP system, particularly in the context of Project Management (PPM) or Project System (PS) modules.
  Cause:
  
  Duplicate Entries: The error is usually caused by duplicate entries in the data being imported or migrated. This can happen if the same WBS element is defined multiple times in the source data.
  Data Integrity Issues: There may be issues with the integrity of the data, such as incorrect relationships or hierarchies between WBS elements.
  Incorrect Mapping: During the migration process, if the mapping of WBS elements is not done correctly, it can lead to duplicates being created under the same parent.
  
  Solution:
  
  Identify Duplicates: Review the source data to identify any duplicate WBS elements. You can use tools like Excel or SQL queries to find duplicates based on WBS element IDs.
  Clean Up Data: Remove or consolidate duplicate entries in the source data before attempting the migration again. Ensure that each WBS element is unique under its parent.
  Check Hierarchies: Verify the hierarchy of WBS elements to ensure that they are structured correctly. Each WBS element should have a unique position under its parent.
  Adjust Migration Mapping: If you are using a migration tool, check the mapping configuration to ensure that it correctly reflects the intended structure of the WBS elements.
  Test Migration: After making the necessary adjustments, perform a test migration with a smaller dataset to ensure that the issue is resolved before migrating the full dataset.
