• What is the cause and solution for SAP error message SDDL_PARSER_MSG328 - Same data type expected for period from "&1" and period to "&2" column ?

  The SAP error message SDDL_PARSER_MSG328 indicates that there is a mismatch in the data types of the "from" and "to" period columns in a data processing context, typically related to time or date fields. This error often arises in scenarios involving data extraction, transformation, or loading (ETL) processes, especially when working with time series data or period-based calculations.
  Cause:
  The error occurs when the system expects both the "from" and "to" period columns to have the same data type, but they do not. This can happen due to:
  
  Incorrect data type definitions in the underlying database or data model.
  Data type mismatches in the source data being processed.
  Configuration issues in the data extraction or transformation logic.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Verify the data types of the "from" and "to" period columns in the relevant data model or database table. Ensure that both columns are defined with the same data type (e.g., both should be of type DATE, TIMESTAMP, etc.).
  
  
  Data Source Validation: If the data is being extracted from an external source, check the source data to ensure that both columns are consistently formatted and of the same type.
  
  
  Transformation Logic: If you are using any transformation logic (e.g., in an ABAP program, a data flow in SAP Data Services, or a BW transformation), ensure that the logic correctly handles the data types and converts them if necessary.
  
  
  Adjust Configuration: If the error is occurring in a specific configuration (like a report or a data extraction process), review the configuration settings to ensure that they are set up correctly to handle the data types.
  
  
  Testing: After making the necessary adjustments, test the process again to ensure that the error is resolved.
