• What is the cause and solution for SAP error message RSLPO_DFG059 - 'Only Get Data Once' set to '&1' ?

  The SAP error message RSLPO_DFG059, which states "Only Get Data Once" set to '&1', typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an issue with data retrieval or data flow in a data model or data extraction process. This error indicates that a certain data retrieval operation is being attempted more than once, which is not allowed in the current configuration.
  Cause:
  
  Duplicate Data Retrieval: The error usually arises when a data source or a data flow is configured to fetch data multiple times for the same request or context, which is not permitted.
  Incorrect Configuration: There may be a misconfiguration in the data model, such as in the InfoProvider or the data flow settings.
  Data Source Settings: The settings for the data source might be set to allow only a single data retrieval operation, and the system is trying to access it again.
  
  Solution:
  
  Check Data Flow Configuration: Review the data flow configuration in the SAP BW system. Ensure that the data source is not being called multiple times unnecessarily.
  Adjust Data Source Settings: If the data source is set to allow only a single retrieval, ensure that your queries or data models are designed to comply with this restriction.
  Review Query Design: If this error occurs during query execution, check the query design in the BEx Query Designer. Ensure that the query is not trying to access the same data source multiple times.
  Debugging: Use transaction codes like RSA1 (Data Warehousing Workbench) to analyze the data flow and identify where the duplication might be occurring.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW or HANA you are using for any known issues or patches that might address this error.
