• What is the cause and solution for SAP error message UJD_EXCEPTION078 - Cannot convert; input data table is empty ?

  The SAP error message UJD_EXCEPTION078: Cannot convert; input data table is empty typically occurs in the context of SAP BusinessObjects or SAP BW when a data processing operation is attempted on an empty dataset. This error indicates that the system expected data to be present for processing, but the input data table was empty.
  Causes:
  
  Empty Data Source: The most common cause is that the data source being queried or processed does not contain any records. This could be due to filters applied that exclude all data or simply because there is no data available in the source.
  Incorrect Query Logic: The query or report logic may be incorrectly set up, leading to no data being returned.
  Data Load Issues: There may have been issues during the data loading process, resulting in an empty dataset.
  Timing Issues: If the data is being loaded in real-time or near real-time, there may be timing issues where the data has not yet been populated when the query is executed.
  
  Solutions:
  
  Check Data Source: Verify that the data source you are querying contains data. You can do this by running a simple query directly against the database or data source.
  Review Filters: Check any filters applied in your query or report. Ensure that they are not overly restrictive and are set up correctly.
  Validate Query Logic: Review the logic of your query or report to ensure it is correctly structured to return the expected results.
  Data Load Verification: If you are using a data warehouse or ETL process, check the logs to ensure that data was loaded successfully and that there were no errors during the load process.
  Timing Adjustments: If the data is being loaded in real-time, consider implementing a delay or a check to ensure that the data is available before executing the query.
