• What is the cause and solution for SAP error message RSUQ321 - No data could be read for selection used ?

  The SAP error message RSUQ321, which states "No data could be read for selection used," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when trying to execute a query or report. This error indicates that the system could not find any data that matches the selection criteria specified in the query.
  Causes:
  
  No Data in the InfoProvider: The most common reason for this error is that there is no data available in the InfoProvider (e.g., InfoCube, DataStore Object) for the specified selection criteria.
  Incorrect Selection Criteria: The selection criteria used in the query may be too restrictive or incorrect, leading to no matching records.
  Data Load Issues: There may have been issues during the data loading process, resulting in missing or incomplete data in the InfoProvider.
  Data Activation Issues: If the data has not been activated properly in the DataStore Object, it may not be available for reporting.
  Time Period Selection: If the query is set to a specific time period where no data exists, this error can occur.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to view the data, leading to the perception that no data exists.
  
  Solutions:
  
  Check Data Availability: Verify that there is data in the InfoProvider for the selection criteria being used. You can do this by running a simple query or using transaction codes like RSA1 to check the data in the InfoProvider.
  Review Selection Criteria: Reassess the selection criteria in the query. Ensure that they are not overly restrictive and that they match the data you expect to retrieve.
  Data Load Monitoring: Check the data load process to ensure that it completed successfully. Use transaction codes like RSMO or RSPC to monitor the data load jobs.
  Data Activation: If using a DataStore Object, ensure that the data has been activated. You can check this in the DataStore Object management area.
  Adjust Time Period: If the query is limited to a specific time period, try expanding the time range to see if data exists outside the specified range.
  Check Authorizations: Ensure that the user executing the query has the necessary authorizations to access the data in the InfoProvider.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSMO (Monitor Data Load), and RSRT (Query Monitor) for troubleshooting.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Query Designer: Use the Query Designer to modify the query and test different selection criteria to identify the issue.
  Documentation: Review SAP documentation for best practices in data modeling and query design to avoid common pitfalls.
