[GNC] One accounting entry, two invoices

[Christian H. Kuhn]

Hi all,

in gnucash-de, noone knew the answer, so i ask here. I use the german 
version of gnucash, so please excuse if a have the menus wrongly translated.

Chess club, non-profit. Account numbers from SKR49 which has been 
standard for non-profit clubs until end of 2024.

A club member pays his membership fees for two years by a single bank 
transfer.

I add the club member as a Customer.

I write two invoices, one for each year. Account is 2110 (membership 
fees < 300€).

I book both invoices. Contra account is 0655 (claims from club matters).

In 0950 (bank account I), i have a split entry.
0950                    240€
          0655                   120€
          0655                   120€

Now i want to assign the payment to the invoices. I hoped that i could 
mark the penultimate line and assign it to one invoice, then mark the 
ultimate line and assign it to the other invoice.

But this fails. When i assign the penultimate line to the proper 
invoice, the amount in the first line is set to 120€, and the last line 
is cleared.

How can i assign the split payment to two invoices?

TIA
