Net Inovice enabled in the contract and after adjustment import Autoinvoice has a error

Hi can anyone help me how to resolve this issue?

Scenario:

• Setup:
  • The Net Invoice option is enabled at both the Contract level and in the Profile option.
  • An amount-based invoice was created.
  • A Projects invoice was generated in Released status for $200.
• Update:
  • The event amount was later updated to $250.
  • A new invoice was created for the net difference of $50 with the tranation source as credit memo
  • The resulting distributions for new credit memo are:
    • +250
    • -200
    • Net 50 (invoice amount)
• Issue:
• When i run Import Autoinvoice process i get the error as below
  • "You can't apply a transaction with a negative amount to another transaction with a negative balance."
