• What is the cause and solution for SAP error message LTR2_CHANGELOG103 - Source data model changed ?

  The SAP error message LTR2_CHANGELOG103 indicates that there has been a change in the source data model of a DataSource that is being used in a Data Transfer Process (DTP) or in a process chain. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when the underlying structure of the data source has been modified, which can lead to inconsistencies in the data loading process.
  Cause:
  
  Change in DataSource Structure: The structure of the DataSource has been altered, such as adding or removing fields, changing data types, or modifying key fields.
  Change in InfoObject: If the InfoObjects used in the DataSource have been modified, it can also trigger this error.
  Inconsistent Data Model: The DTP or process chain is trying to load data based on an outdated model that no longer matches the current structure of the source data.
  
  Solution:
  To resolve the LTR2_CHANGELOG103 error, you can follow these steps:
  
  
  Check DataSource Changes:
  
  Review the changes made to the DataSource in the SAP BW system. This can be done by checking the DataSource definition in the Data Warehousing Workbench (transaction RSA1).
  If changes were made, ensure that they are intended and necessary.
  
  
  
  Update DTP:
  
  If the DataSource has changed, you may need to update the DTP that is using this DataSource. This can involve:
  
  Re-activating the DTP.
  Adjusting the field mappings in the DTP to align with the new structure of the DataSource.
  
  
  
  
  
  Check Process Chains:
  
  If the DTP is part of a process chain, ensure that the process chain is also updated to reflect the changes in the DataSource.
  You may need to re-activate the process chain.
  
  
  
  Re-activate InfoObjects:
  
  If InfoObjects have been modified, ensure that they are re-activated. This can be done in the InfoObject maintenance area.
  
  
  
  Test the Data Load:
  
  After making the necessary adjustments, test the data load again to ensure that the error has been resolved.
  
  
  
  Consult Documentation:
  
  If you are unsure about the changes made or how to proceed, consult the SAP documentation or reach out to your SAP support team for assistance.
