• What is the cause and solution for SAP error message GU920 - No differences were found between the two tables ?

  The SAP error message GU920, which states "No differences were found between the two tables," typically occurs during a comparison process, such as when using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to compare two database tables or when performing a data migration or replication task.
  Cause:
  
  No Data Differences: The primary cause of this message is that the two tables being compared do not have any differences in their data. This means that the records in both tables are identical based on the criteria used for comparison.
  Incorrect Comparison Criteria: If the criteria for comparison are not set correctly, it may lead to the perception that there are no differences when, in fact, the criteria are too restrictive or not aligned with the data structure.
  Empty Tables: If one or both of the tables being compared are empty, the system will return this message since there are no records to compare.
  Technical Issues: There could be underlying technical issues, such as database locks or inconsistencies, that might affect the comparison process.
  
  Solution:
  
  Verify Data: Check the contents of both tables to ensure that they indeed contain data and that the data is expected. Use transaction codes like SE16 or SE11 to view the records.
  Review Comparison Criteria: Ensure that the criteria used for comparison are appropriate. Adjust the selection conditions if necessary to include more records or to align with the data structure.
  Check for Empty Tables: Confirm that both tables have records. If one is empty, you may need to populate it with the necessary data before performing the comparison.
  Database Consistency: If you suspect technical issues, check for database locks or inconsistencies. You may need to consult with your database administrator or perform a database consistency check.
  Use Alternative Tools: If the built-in comparison tools are not yielding the expected results, consider using alternative tools or methods for data comparison, such as custom ABAP programs or third-party data comparison tools.
