• What is the cause and solution for SAP error message RSLPO_DFG151 - 'Only Retrieve Last Request' (='&1') is consistent ?

  The SAP error message RSLPO_DFG151, which states "Only Retrieve Last Request" (='&1') is consistent, typically occurs in the context of data extraction or data loading processes, particularly when working with SAP BW (Business Warehouse) or SAP Data Services. This error indicates that the system is trying to retrieve data from a request that is not the most recent one, which is not allowed in certain scenarios.
  Cause:
  
  Request Consistency: The error usually arises when there is an attempt to retrieve data from a request that is not the last one processed. In SAP BW, data requests are often processed in a sequence, and only the most recent request can be accessed for certain operations.
  Data Load Issues: If there are issues with data loads or if the data model has been changed, it may lead to inconsistencies in the requests.
  Data Source Configuration: The configuration of the data source or the InfoProvider may restrict access to only the latest request.
  
  Solution:
  
  Check the Request: Ensure that you are trying to access the most recent data request. You can do this by checking the request history in the Data Warehousing Workbench (transaction RSA1) or the relevant InfoProvider.
  Reprocess the Data Load: If the data load has failed or is inconsistent, you may need to reprocess the data load to ensure that the latest request is valid and accessible.
  Adjust Data Source Settings: Review the settings of the data source or InfoProvider to ensure that they allow access to the latest request. This may involve checking the extraction settings or the data flow configuration.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP BW you are using, as there may be version-specific considerations or patches that address this issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSRV (Consistency Check), and others that can help in troubleshooting.
