  The SAP error message IU448 ("Table & already contains entries") typically occurs when you are trying to insert or update data in a table that already has existing entries, and the operation you are attempting does not allow for duplicates or conflicts with existing data.
  Cause:
  
  Duplicate Entries: The table you are trying to modify already contains entries that conflict with the new data you are trying to insert.
  Primary Key Violation: If the table has a primary key or unique constraint, attempting to insert a record with a key that already exists will trigger this error.

  Solution:
  
  Check Existing Data: Before inserting or updating, check the existing entries in the table to ensure that the data you are trying to add does not already exist.
  Modify the Data: If the data already exists and you need to update it, consider using an UPDATE statement instead of an INSERT.
  Remove Duplicates: If duplicates are not allowed, you may need to remove or modify the existing entries that are causing the conflict.
  Review Constraints: Check the table's constraints and ensure that your data complies with them. If necessary, adjust your data or the constraints.
