transaction.scm date subtotal options - calling wizards ...

[Christopher Lam]

Hi John,



The origin of this project comes from my wish to produce report... "how
much did I spend on various categories, in this quarter?"


Source account=Asset:Bank.

Prime-sortkey=date

Prime-subtotal=quarterly

Sec-sortkey=other-accname

Sec-subtotal=true



2016Q1

Expense:Groceries

01/01/16 – Allmart $200

01/02/16 – Qmart $300

01/03/16 – Nomart $300

*Subtotal Expense:Groceries $800*

Expense:Petrol

15/01/16 – Coral $300

15/02/16 – BQ $250

* Subtotal Expense:Petrol $550*

* Subtotal 2016Q1 = $1350*



However the current query mechanism means that the dates will be split up,
because, although they belong to the same quarter, they have different
dates.

qof-query mechanism cannot sort by quarter... can only sort by date.


I attach 2 screenshots to illustrate and the sample test file. This is my
amended transaction.scm and the original/custom sorter can be chosen in the
checkbox.
