I wanted to mention that when we have two folios seperated out as Room/Tax (A) and Incidental (B) , 

the charges for extras get attached to guest profile (A) when checking in the guest. However, after night audit the charge gets posted in Incidentals (B) folio. 

So, if there was daily pet fee or rollaway bed, the amount would be authorized in A while checking in a guest. Then, since it will get posted in B we need to charge the guest again in folio B while checking out the guest.
