Orphan Accruals as a result of changing 2 Way to 3 Way and Vice Versa

Summary

Need to understand the behavious of Receipt Accruals in these situations

Content

We are in the requirements phase and I am not able to test the following scenarios to see how Fusion handles them.

- The client want to create accruals at  receipt stage

- When they enter an invoice and there are no recipts, they want to accrue for the whole invoice and then they want this accrual to be balanced off by any receipt accruals the next time the invoice is validated

So please advise on the scenarios below based on the requirements above :

1. Scenario 1 :

- 2 way Match PO. 1 line - Order Qty 10.
