Cashflow Report on Split Transactions in Checking Accounts

[casi]

Hi,

I am running a standard cashflow report on a singe account which is a
checking account, selected in the report options.

This checking account receives my net salary transactions which are part
of split transactions.
These split transactions, I enter them in an income account, splitting
the gross value in  transactions for taxes and other deductions which
are transferred to separate expense accounts. The net income is the only
value from that split that goes into the checking account.

I do see, that in the checking account the complete split is accessible,
even though the top line only contains the vet salary value (and
therefore is correctly contributing to the checking account balance).

Still, when running the cashflow report on this checking account, I
would expect that in the area "Money into selected accounts comes from"
- in the line of the income account -  only the sum of the net values is
shown (i.e. what I really can turn into cash).

Instead, what is listed in the report is the gross value. (As also the
tax deductions are listed here, the final balance is correct again.)

I get what I want when I run the cashflow report on the income account
selected as the only account. In that case I see the net value in the
area "Money out of selected accounts goes to", but that this is the only
way to see this value is not what I expected.

Question:
Bug or wrong expectation?

Thanks and kind regards,
Carsten
