• What is the cause and solution for SAP error message RSTRAN_T001 - No source fields available ?

  The SAP error message RSTRAN_T001 No source fields available typically occurs during the process of data extraction or transformation in SAP BW (Business Warehouse) or when working with data transfer processes (DTPs). This error indicates that the system cannot find any source fields to map to the target fields in the data flow.
  Causes:
  
  Missing Source Fields: The most common cause is that the source data source does not have any fields defined or available for extraction.
  Incorrect Data Source Configuration: The data source may not be properly configured, leading to a lack of available fields.
  Data Source Activation: The data source might not be activated, which can prevent the fields from being recognized.
  Field Mapping Issues: There may be issues with the mapping between the source and target, such as missing or incorrectly defined transformations.
  Data Source Type: The type of data source (e.g., InfoSource, DataSource) may not be compatible with the target structure.
  Authorization Issues: Lack of proper authorizations to access the source fields can also lead to this error.
  
  Solutions:
  
  
  Check Data Source Configuration:
  
  Go to the Data Source in the SAP BW system and ensure that it is correctly configured and activated.
  Verify that the source fields are defined and available for extraction.
  
  
  
  Activate Data Source:
  
  If the data source is not activated, activate it in the Data Warehousing Workbench (transaction RSA1).
  
  
  
  Review Field Mapping:
  
  Check the transformation rules between the source and target. Ensure that all necessary fields are mapped correctly.
  If necessary, adjust the transformation to include the required fields.
  
  
  
  Check for Authorizations:
  
  Ensure that the user executing the data transfer has the necessary authorizations to access the source fields.
  
  
  
  Test Data Source:
  
  Use transaction RSA3 to test the data source and see if it returns any data. This can help identify if the issue is with the data source itself.
  
  
  
  Consult Logs:
  
  Review the logs for any additional error messages or warnings that may provide more context about the issue.
  
  
  
  Recreate Data Source:
  
  If the problem persists, consider recreating the data source or transformation to ensure that all settings are correct.
