• What is the cause and solution for SAP error message RSDS189 - Data format of delta field &1 not compatible with timestamp ?

  The SAP error message RSDS189 indicates that there is a data format issue with a delta field that is expected to be in a timestamp format but is not compatible. This error typically arises in the context of data extraction processes, particularly when working with DataSources in SAP BW (Business Warehouse) or when dealing with delta loads.
  Cause:
  The error can occur due to several reasons:
  
  Data Type Mismatch: The delta field in the source system may not be in the expected timestamp format. For example, it might be in a string format or a different date format that cannot be interpreted as a timestamp.
  Incorrect Configuration: The DataSource or InfoSource may be incorrectly configured, leading to mismatches in expected data types.
  Data Quality Issues: There may be invalid or corrupted data in the source system that does not conform to the expected timestamp format.
  Changes in Source System: If there have been changes in the source system (like changes in the database schema or data types), it can lead to this error.
  
  Solution:
  To resolve the RSDS189 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Verify the DataSource settings in SAP BW. Ensure that the delta field is correctly defined as a timestamp in the DataSource.
  Check the field mapping in the InfoPackage to ensure that the delta field is mapped correctly.
  
  
  
  Data Type Validation:
  
  Inspect the data in the source system to ensure that the delta field is indeed in the correct timestamp format. You may need to convert or format the data appropriately in the source system.
  
  
  
  Data Cleansing:
  
  If there are invalid entries in the delta field, you may need to cleanse the data in the source system. This could involve removing or correcting invalid records.
  
  
  
  Test Extraction:
  
  After making the necessary changes, perform a test extraction to see if the error persists. Monitor the logs for any additional errors or warnings.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource you are working with. There may be known issues or additional configuration steps required.
