[GNC] Two invoices, two customers, one bank transfer

[Christian H. Kuhn]

Hi all,

Scenario: small chess club. Parent pays membership fees for their children by 
one bank transfer. There is one customer entry and one invoice per child (one 
pays the adult fee, the other the reduced fee).

SKR 49, german account plan for non-profit-organizations.

I can split the bank transfer entry:

per 0950 Bank 180 €
                to 0655 Claims from club Matters 120 € (Child 1)
                to 0655 Claims from club Matters 80 € (Child 2)

If  i assign the payment to one invoice, the whole amount is assigned. I can 
avoid it by changing the to account of the second part to p.e. 1990 Deferred 
income, and then make a second entry per 1990 to 0655 80€ that i can assign to 
the 2nd invoice.

Of course this works per saldo. But that is not what is 1990 for, and there 
exists no other account that is for „parking“ a sum waiting for being 
assigned.

What is the canonical way to assign one bank transfer to two invoices of two 
different customers?

TIA
