• What is the cause and solution for SAP error message 00959 - DB error: In Table &, field & is unknown ?

  The SAP error message "00959 DB error: In Table &, field & is unknown" typically indicates that there is an issue with a database table or field that the system is trying to access. This error can occur for several reasons, and understanding the cause is essential for finding a solution.
  Causes:
  
  
  Field or Table Does Not Exist: The specified field or table may not exist in the database. This could be due to a typo in the field or table name, or the table may not have been created yet.
  
  
  Database Schema Changes: If there have been recent changes to the database schema (e.g., a table was dropped or a field was removed), the application may still be trying to access the old structure.
  
  
  Transport Issues: If the changes were transported from one system to another (e.g., from development to production), there may have been issues during the transport process that caused the table or field to not be created properly.
  
  
  Authorization Issues: The user may not have the necessary authorizations to access the specified table or field.
  
  
  Data Dictionary Issues: There may be inconsistencies in the data dictionary, such as missing entries or corruption.
  
  
  Solutions:
  
  
  Check Table and Field Names: Verify that the table and field names specified in the error message are correct. Look for typos or incorrect references.
  
  
  Verify Database Schema: Use transaction codes like SE11 (Data Dictionary) to check if the table and field exist in the database. If they do not exist, you may need to create them or restore them from a backup.
  
  
  Review Transport Logs: If the issue arose after a transport, check the transport logs for any errors or warnings that may indicate why the table or field was not created.
  
  
  Check Authorizations: Ensure that the user has the necessary authorizations to access the table and field. You can use transaction SU53 to analyze authorization issues.
  
  
  Data Dictionary Consistency Check: Use transaction SE14 to perform a consistency check on the database objects. This can help identify and resolve any inconsistencies.
  
  
  Rebuild the Table: If the table is missing or corrupted, you may need to recreate it. This should be done with caution and typically requires a backup of the data.
