Impact of transaction dates for miscellaneous transactions for PMAC costing method organization

One of our clients is using periodic average costing and the open period is Nov 23, while client wanted to perform few transactions in November itself. But while creating miscellaneous transactions somehow user forgot to change system date and issue transaction was processed in Jan 24 instead of Nov 23. Now to rectify this we are in the thought of reversing it by performing receipt transaction for the same quantity with system date. Later perform the required transactions with November date. Does this impact when Jan 24 period gets open.

In perpetual cost method layers get created, where as Periodic Average Cost method doesn't have any layers.
