  The SAP error message MW321 typically indicates an issue related to the insertion of data into a table, often involving a key that is not valid or does not exist. This error can occur in various contexts, such as during the execution of a transaction, report, or program that attempts to insert data into a database table.
  Cause:
  
  Invalid Key: The key specified in the error message does not exist in the table you are trying to insert data into. This could be due to a typo or an incorrect reference.
  Duplicate Key: The key you are trying to insert already exists in the table, violating the unique constraint.
  Data Consistency Issues: There may be issues with data consistency, such as foreign key constraints not being met.
  Authorization Issues: The user may not have the necessary authorizations to perform the insert operation.

  Solution:
  
  Check the Key: Verify that the key you are trying to insert is correct and exists in the relevant tables. Ensure there are no typos or incorrect references.
  Check for Duplicates: If the key already exists, you may need to update the existing record instead of inserting a new one.
