credit memo's which are rejected wrongly and moved to draft will impact period closure of PPM

Summary:

credit memo's which are rejected wrongly and moved to draft will impact period closure of PPM.

User created a credit memo for a contract invoice which was already interfaced to receivables and in Accepted status. And realized he selected the wrongly invoice while cancelling the invoice. Users doesn't want to impact the invoice and hence rejected the credit memo and returned to draft status.

Will it impact the period closing in which the credit memo is raised?

Do we get any error saying the created invoice is not interfaced to AR and from draft status if we want to delete the credit memo is that possible?
