Shows the reference details while allocate customer credits. 

Most of the time, customers return the stocks, which come with a reference number. The stocks they returned can be from different sales orders but under one reference number. When the customers want to use their credit, they will provide us with the reference number.

Hence, by using the reference number they provide, we will allocate the credit accordingly. We have include reference number in the reference column while creating the credit notes. However, the reference column is not showing in the “Use Customer Credit”, and this does not make sense.
