• What is the cause and solution for SAP error message LTR2_DS_CHG_CONV002 - Sumup Type was changed ?

  The SAP error message LTR2_DS_CHG_CONV002 indicates that the sum-up type for a data source has been changed. This typically occurs in the context of data extraction and transformation processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error is triggered when there is a mismatch between the expected sum-up type of a data source and the actual sum-up type that has been defined or changed in the system. This can happen due to:
  
  Changes in Data Source Configuration: If the configuration of the data source has been modified, such as changing the sum-up type from a specific aggregation method to another.
  Data Model Changes: Changes in the underlying data model or InfoObjects that affect how data is aggregated.
  Transport Requests: If changes were transported from one system to another (e.g., from development to production), and the sum-up type was altered in the process.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Source Configuration:
  
  Go to the Data Source in the SAP BW system and verify the sum-up type settings.
  Ensure that the sum-up type is correctly configured according to your requirements.
  
  
  
  Adjust Data Model:
  
  If the data model has changed, ensure that all dependent objects (like InfoProviders, queries, etc.) are updated accordingly.
  Check if any transformations or DTPs (Data Transfer Processes) need to be adjusted to accommodate the new sum-up type.
  
  
  
  Re-activate Data Source:
  
  Sometimes, simply reactivating the data source can resolve the issue. This can be done in the Data Warehousing Workbench.
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings related to the data source or its configuration.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific data source and sum-up types for any additional guidance or known issues.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the data extraction and reporting processes work as expected without errors.
