  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_LIST021 Document &1: Table &2 is empty (Comparison is not possible)
  
  Meaning / Cause:
  This error occurs during the execution of a report or transaction where the system expects data in a particular internal table (denoted by &2) related to a document (denoted by &1), but finds that the table is empty. Because the table is empty, the system cannot perform a comparison or further processing, leading to this message.
  Common scenarios include:
  
  When running reconciliation or comparison reports (e.g., asset accounting, FI-CA, or other financial modules) where the system compares data from two sources.
  The document number (&1) is provided, but the corresponding data extraction or selection step did not retrieve any entries into the internal table (&2).
  Possible reasons for the empty table:
  
  The document does not exist or is not posted.
  The selection criteria/filter used in the report exclude all relevant entries.
  Data inconsistencies or missing master data.
  Authorization issues preventing data retrieval.
  Technical issues like missing or incomplete data load.
  
  
  
  
  Solution / How to Fix:
  
  
  Check Document Existence:
  
  Verify that the document number (&1) exists in the system and is posted correctly.
  Use transaction codes like FB03 (Display Document) or relevant module-specific display transactions.
  
  
  
  Review Selection Criteria:
  
  Ensure that the selection parameters used in the report or transaction are correct and not overly restrictive.
  Try broadening the selection to see if data appears.
  
  
  
  Check Data Consistency:
  
  Run consistency checks or reports to verify that the data related to the document is complete.
  For example, in Asset Accounting, check asset master data and postings.
  
  
  
  Authorization Check:
  
  Confirm that the user running the report has the necessary authorizations to view the data.
  
  
  
  Debugging / Technical Analysis:
  
  If you have access, debug the program/report to see why the internal table (&2) is empty.
  Check the data retrieval logic and database selects.
  
  
  
  Consult SAP Notes:
  
  Search for SAP Notes related to the specific module and error message for any known bugs or patches.
  
  
  
  Re-run or Reprocess:
  
  If the error is due to temporary data issues, try re-running the process or reprocessing the document.
  
  
  
  
  Related Information:
  
  This message is informational but indicates that the process cannot continue due to missing data.
  The message is often seen in reconciliation or comparison reports where two data sets are compared.
  The placeholders &1 and &2 will be replaced by the actual document number and table name in the runtime message.
  Example:
  
  WZRE_LIST021 Document 4900001234: Table ZTABLE is empty (Comparison is not possible)
  
  
  Summary:

  Solution
  Verify document existence, check selection criteria, ensure data consistency, check authorizations, debug if needed.
  
  
  Related Info
  Common in reconciliation/comparison reports; placeholders &1 = document, &2 = table name.
