• What is the cause and solution for SAP error message RSDL019 - Name of field & changed in the database ?

  The SAP error message RSDL019 indicates that the name of a field has changed in the database, which can lead to issues in reports, queries, or data extraction processes that rely on the original field name. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA environments where data models and structures are defined.
  Cause:
  
  Field Renaming: The field in the underlying database has been renamed, which can happen due to changes in the data model, updates to the source system, or modifications made by developers.
  Data Source Changes: If the data source (like an InfoProvider or a DataSource) has been modified, it may lead to discrepancies in the field names expected by existing queries or reports.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), and the transport did not include all necessary changes, it could lead to this error.
  
  Solution:
  
  Check Field Name Changes: Verify the database schema or the data source definition to confirm the new field name. You can do this by checking the relevant tables or data sources in the SAP system.
  Update Queries/Reports: If the field name has changed, you will need to update any queries, reports, or data models that reference the old field name. This may involve modifying the query definitions in SAP BW or adjusting the data extraction logic.
  Re-activate DataSources: If the issue is related to a DataSource, try reactivating the DataSource in the SAP BW system to ensure it reflects the current database structure.
  Check Transport Requests: If the issue arose after a transport, ensure that all related objects were included in the transport request and that the transport was successful.
  Consult Documentation: Review any documentation or change logs related to the data model or database changes to understand the context of the field name change.
  
  Related Information:
