• What is the cause and solution for SAP error message DDLS_HIER059 - Datatype for valid_to &1 is not as data type for period_to &2 ?

  The SAP error message DDLS_HIER059 indicates a mismatch in data types between two fields, specifically valid_to and period_to. This error typically arises in the context of data modeling or when working with hierarchical data structures in SAP, such as when defining InfoObjects in SAP BW or when working with data definitions in ABAP Dictionary.
  Cause:
  The error occurs when the data type of the field valid_to does not match the expected data type of the field period_to. This can happen due to:
  
  Inconsistent Data Types: The two fields may have been defined with different data types in the underlying database or data model.
  Incorrect Field Mapping: During the creation or modification of a data model, the fields may have been incorrectly mapped or defined.
  Changes in Data Model: If there were recent changes to the data model or database schema, it could lead to inconsistencies.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Types: Verify the data types of both valid_to and period_to. Ensure that they are compatible. For example, if one is defined as a date and the other as a timestamp, you may need to adjust one of them.
  
  
  Modify Data Model: If you find that the data types are indeed different, you may need to modify the data model to ensure that both fields have the same data type. This may involve changing the field definitions in the ABAP Dictionary or the InfoObject settings.
  
  
  Recreate or Adjust Mappings: If the fields are part of a mapping or transformation process, ensure that the mappings are correctly set up to handle the data types appropriately.
  
  
  Check for Updates: If you are working in a development environment, ensure that all changes have been transported correctly and that there are no pending updates that could affect the data model.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific version you are using, as there may be known issues or additional guidance on resolving this error.
