  The SAP error message "TREX_EXT_PE000 Request &1: Aggregated sum of reference key figure = 0" typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when there is an issue with the data aggregation process in the context of a query or data extraction. This error indicates that the aggregated sum of a reference key figure is zero, which can lead to issues in reporting or data processing.
  Causes:
  
  Data Availability: The most common cause is that there is no data available for the reference key figure in the specified time period or selection criteria.
  Incorrect Aggregation Logic: The aggregation logic defined for the key figure may not be correctly set up, leading to an unexpected result of zero.
  Data Source Issues: There may be issues with the data source from which the key figure is being derived, such as missing or incorrect data.
  Filters and Selections: Filters applied in the query or report may be too restrictive, resulting in no data being returned for the key figure.
  Data Load Issues: There may have been issues during the data load process, such as errors in the extraction, transformation, or loading (ETL) process.
  
  Solutions:
  
  Check Data Availability: Verify that there is data available for the reference key figure in the relevant time frame. You can do this by running a query or checking the underlying data source.
  Review Aggregation Logic: Ensure that the aggregation logic for the key figure is correctly defined. Check the settings in the InfoObject or the query definition.
  Examine Filters: Review any filters or selection criteria applied in the query. Try removing or adjusting them to see if data is returned.
  Data Source Validation: Check the data source for any issues. Ensure that the data is being loaded correctly and that there are no errors in the data extraction process.
  Reprocess Data: If there are issues with the data load, consider reprocessing the data. This may involve re-running the data extraction and loading processes.
  Check for Null Values: Ensure that there are no null or missing values in the key figure that could be affecting the aggregation.
