• What is the cause and solution for SAP error message 0Q082 - The sources differ only in empty rows ?

  The SAP error message 0Q082 ("The sources differ only in empty rows") typically occurs during data extraction or transformation processes, particularly when working with SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This error indicates that the data sources being compared or merged contain only empty rows, which means there is no meaningful data to process.
  Cause:
  
  Empty Data Sources: The primary cause of this error is that one or more of the data sources being used in the query or transformation contain only empty rows. This can happen if the data extraction process did not retrieve any records due to filters, selection criteria, or if the source system has no data.
  Incorrect Data Selection: The selection criteria applied in the data extraction might be too restrictive, leading to no data being fetched.
  Data Source Configuration: There may be issues with the configuration of the data source, such as incorrect mappings or settings that prevent data from being extracted properly.
  
  Solution:
  
  Check Data Sources: Verify the data sources involved in the query or transformation. Ensure that they contain valid data and are not empty. You can do this by running a simple query or report on the data source to see if any records are returned.
  Review Selection Criteria: Examine the selection criteria used in the data extraction process. Make sure that the filters are not too restrictive and that they allow for the retrieval of relevant data.
  Data Source Configuration: Check the configuration of the data source in SAP BW/BI. Ensure that all mappings and settings are correct and that the data source is properly connected to the underlying data.
  Data Load Process: If the data source is supposed to have data but is returning empty rows, check the data load process. Ensure that the data is being loaded correctly from the source system and that there are no errors in the data load process.
  Consult Logs: Review any logs or error messages related to the data extraction process. This can provide insights into what might be going wrong.
