Refund - Receivables

Hi all,

My client collects a refundable deposit when a customer registers. Initially, a receipt is entered to record the deposit.

Example

Customer pays LKR 1000 as a deposit.

Confirmed cash a/c Dr 1000

Unapplied cash(refundable deposit a/c) a/c Cr 1000

The receipt is remitted and reconciled on the same day.

Cash a/c Dr 1000

Confirmed cash a/c Cr 1000

The agreement of the customer is terminated on 30-Nov-2020 and deposit needs to be refunded to the customer.

Unapplied cash(refundable deposit a/c) a/c Dr 1000

Refund control a/c Cr 1000

My concerns are,

1. Why does the system only allow to maintain one receivable activity type for refund?
