  The SAP error message RSDS342 indicates that a DataSource (or InfoSource) is being dropped and recreated due to changes made to its structure or properties. This typically occurs in the context of SAP BW (Business Warehouse) when there are modifications to the underlying data model that affect the DataSource.
  Cause:
  The error message RSDS342 is triggered when:
  
  Structural Changes: Changes have been made to the structure of the DataSource, such as adding or removing fields, changing data types, or modifying field properties.
  Metadata Changes: Changes in the metadata of the DataSource that require a complete refresh of the DataSource.
  DataSource Activation: The DataSource is being activated after changes have been made, which necessitates dropping the existing DataSource and creating a new one.

  Check Data Transfer: After the DataSource is recreated, ensure that data transfer processes (DTPs) and any related processes are updated to reflect the new structure.
  
  
  Test: After the DataSource has been recreated, perform tests to ensure that data extraction and reporting are functioning as expected.
