General parameters > Chapter Accounting > Parameter LOWMTCGEN (Exch. rate var./Low matching) 

Use this parameter to control currency variance behavior when posting partial payments. The default value is No. For a partial payment, a journal entry line calculating the difference between the invoice currency and the payment currency is not generated. The automatic journal entry is only generated for full payments, therefore only for a complete match to the open item.

If you want to generate the journal entry that shows the currency variance for a partial payment (partial matching), you need to set this parameter to Yes.
