System should allow to post invoices in different currencies for the same charge type.

Example: Shipment from USA to KSA.(2 different freight forwarders)

Their are freight charges incurred in USA paid in USD and similarly local freight charges paid in SAR. Which ever invoice is posted first the later would hinder posting invoice journal with below infolog.

"Cost type Freight Forwarder: Cost transaction currency can't be changed because its has been previously invoiced".
