AR Transaction Dates Mismatch - Transaction/GL/Ship Dates

Summary:

Hi there, we are seeing an issue where invoice dates do not match the ship-date and if an accounting period is closed when the order was first entered, it posts to the 1st of the following open period. Is there a way to change this to the invoice date is always the ship-date, no matter what?

This is only happening on transactions where the sales order was created in a closed period. If the transaction date is derived from the ship-date, why is the system trying to use the order date to check accounting periods? There must be a way to fix that.
