• What is the cause and solution for SAP error message RSDS340 - Conversion type &2 not supported for field &1 ?

  The SAP error message RSDS340 indicates that there is an issue with the conversion type for a specific field in a DataSource. This error typically arises when the system encounters a field that has a conversion type that is not supported for the data extraction process.
  Cause:
  The error can occur due to several reasons:
  
  Unsupported Conversion Type: The field in question has a conversion type that is not recognized or supported by the DataSource or the extraction process.
  Data Type Mismatch: There may be a mismatch between the data type of the field in the source system and what is expected in the target system.
  Incorrect DataSource Configuration: The DataSource may not be configured correctly, leading to issues in how fields are interpreted during extraction.
  Changes in Data Model: If there have been recent changes to the underlying data model (e.g., changes in the database schema), it may lead to unsupported conversion types.
  
  Solution:
  To resolve the RSDS340 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP system and verify the field definitions and their conversion types.
  Ensure that the field types are correctly defined and supported.
  
  
  
  Review Field Mappings:
  
  Check the mappings between the source fields and the target fields in the DataSource.
  Make sure that the conversion types are compatible.
  
  
  
  Modify Conversion Types:
  
  If you identify unsupported conversion types, consider modifying them to supported types. This may involve changing the data type in the source system or adjusting the DataSource configuration.
  
  
  
  Update DataSource:
  
  If the DataSource is outdated or has not been updated to reflect changes in the underlying data model, consider reactivating or regenerating the DataSource.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource and its supported conversion types for further guidance.
  
  
  
  Testing:
  
  After making changes, perform a test extraction to ensure that the error is resolved and that data is being extracted correctly.
