Individual Compl Plan transaction is split in 2 records if startdate and amount is changed

Summary:

A user has submitted an INDIVIDUAL COMPENSATION PLAN entry. Later the start date and amount is changed on the same transaction. The system is creating 2 records. We have found in document KB51749 that this is expected behaviour. I need to understand the product design or business scenario where the record should be split instead of correcting the current transaction
