  The SAP error message CNV_PE868 indicates that a single insert operation into a specified table has failed multiple times. This error typically occurs during data migration or conversion processes, often when using SAP's Data Migration tools or during system upgrades.
  Causes:
  
  Data Integrity Issues: The data being inserted may violate constraints such as primary keys, foreign keys, or unique constraints in the target table.
  Data Type Mismatches: The data types of the source and target fields may not match, leading to conversion errors.
  Missing Required Fields: Required fields in the target table may not be populated in the source data.
  Locking Issues: The target table may be locked by another process, preventing the insert operation from completing.

  Insufficient Authorizations: The user executing the insert may not have the necessary permissions to write to the target table.
  
  Solutions:
  
  Check Data Integrity: Review the data being inserted to ensure it adheres to the constraints of the target table. Look for duplicates, null values in required fields, and ensure that foreign key relationships are maintained.
  Data Type Validation: Ensure that the data types in the source match those in the target table. If necessary, perform data transformations to align the types.
  Populate Required Fields: Make sure that all required fields in the target table are being populated with valid data.
  Check for Locks: Investigate if the target table is locked by another transaction. You can use transaction codes like SM12 to check for locks.
  Review Database Constraints: Check for any database constraints that might be causing the insert to fail. This can include unique constraints or check constraints.
  Authorization Check: Ensure that the user executing the operation has the necessary authorizations to perform the insert.
