how can we check what is the active and in use pricing algorithm?

from what we can see, all the version 1 of the pricing algorithm are showing with the recent date. however, we need the latest version to be showing with the latest date and is currently being used. please help in checking this as we are cannot submit any sales order as we are encountering this error:

An order was not created because a value was not provided for the required attribute HeaderCurrencyCode in the source order with the following details: source order XXXXXXX, source order line 1, source order schedule 1, source order charge XXXXXXXXXXXXXX, source order charge component XXXXXXXXXXXXXXX. Provide the required value, and resubmit the order.
