What is the effect of not running the receipt accrual process while having accrue at period end POs

The requirement is to

1- Create and receive an expense PO.

2- Receiving this PO will not create any journals.

3- The only journals generated will be from the AP invoice

3- PO charge account will be the debit side in the ERS invoice.

We can do that by unchecking the accrue at receipt check box in the PO schedule, but if the PO was received and not invoiced before the accounting period ends the receipt journals will be created upon running the create receipt accrual process and then reversed in the next period.

I need to know the effect of not running the receipt accrual process at all.
