• What is the cause and solution for SAP error message DDLS_HIER058 - Datatype for valid_from &1 is not as data type for period_from &2 ?

  The SAP error message DDLS_HIER058 indicates a mismatch in data types between two fields in a hierarchy structure, specifically between valid_from and period_from. This error typically arises when you are trying to create or modify a hierarchy in SAP BW (Business Warehouse) or similar systems where time-dependent data is involved.
  Cause:
  The error occurs when:
  
  The data type of the valid_from field does not match the expected data type of the period_from field.
  This can happen if the fields are defined with different data types in the underlying database or if there is a mismatch in the data model configuration.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types:
  
  Verify the data types of both valid_from and period_from fields in the data model. They should be compatible (e.g., both should be of type DATE or TIMESTAMP).
  
  
  
  Adjust Data Model:
  
  If there is a mismatch, you may need to adjust the data model to ensure that both fields have the same data type. This may involve modifying the data element or structure in the ABAP Dictionary (SE11).
  
  
  
  Recreate or Adjust Hierarchy:
  
  If the hierarchy was created with incorrect field definitions, you may need to delete and recreate the hierarchy or adjust the existing hierarchy to ensure that the fields are correctly defined.
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, ensure that all related objects were transported correctly and that there are no inconsistencies in the target system.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to hierarchy definitions and data types to ensure compliance with best practices.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the hierarchy creation or modification again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or RSA1 (Data Warehousing Workbench) to check and modify the data model.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  Data Model Documentation: Review the data model documentation for your specific implementation to understand the expected data types and structures.
  
  By following these steps, you should be able to identify and resolve the cause of the DDLS_HIER058 error in your SAP environment.
