• What is the cause and solution for SAP error message R8458 - Metadata inconsistencies between DataSource and hier. additional info ?

  The SAP error message R8458 indicates that there are metadata inconsistencies between a DataSource and its associated hierarchy. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there are discrepancies in the structure or definitions of the DataSource and the hierarchy it is supposed to work with.
  Causes of Error R8458
  
  
  Changes in DataSource: If the DataSource has been modified (e.g., fields added, removed, or changed) without corresponding updates to the hierarchy, inconsistencies can arise.
  
  
  Hierarchy Changes: If the hierarchy structure has been altered (e.g., nodes added or removed) without updating the DataSource, this can lead to mismatches.
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production) and not all related objects were included, inconsistencies may occur.
  
  
  Versioning Issues: If different versions of the DataSource and hierarchy are being used, this can lead to discrepancies.
  
  
  Solutions to Error R8458
  
  
  Check Metadata: Review the metadata of both the DataSource and the hierarchy to identify discrepancies. Ensure that the fields and structures match.
  
  
  Re-activate DataSource: Sometimes, simply reactivating the DataSource can resolve the issue. This can be done in the DataSource maintenance transaction (e.g., RSA1).
  
  
  Update Hierarchy: If the hierarchy has changed, ensure that it is updated to reflect the current structure of the DataSource. This may involve adding or removing nodes or attributes.
  
  
  Transport Consistency: Ensure that all related objects were transported together. If not, transport the missing objects to maintain consistency.
  
  
  Use SAP Notes: Check for any relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues.
  
  
  Recreate Hierarchy: In some cases, it may be necessary to recreate the hierarchy if it is significantly out of sync with the DataSource.

  Support Community: Engage with the SAP Community or forums for additional insights and solutions from other users who may have encountered similar issues.
