Trouble with Balance Assertions/Assignments #538
Description
Maybe I am missing something, but I seem to be having issues with balance assertions/assignments. I am trying to track my starbucks points. Sometimes points are earned through spending, and sometimes there are bonus points. My plan was to use automatic transactions for stars earned through spending and then just set the balance to zero (or whatever the balance is after redeeming) when the points are redeemed. Here is the test journal I have put together.
; -*- ledger -*-
account Awards:Starbucks:Earned
account Awards:Starbucks:Balance
account Awards:Starbucks:Redeemed
commodity $
note United States Dollars
format $1,000.00
nomarket
default
= @/^Starbucks/ and /Coffee/
Awards:Starbucks:Earned (-0.5 SB * amount)
Awards:Starbucks:Balance ( 0.5 SB * amount)
2017-01-01 * Starbucks (Card Reloaded)
Expenses:Coffee 50.00 USD
Liabilities:Cash
2017-01-03 * Starbucks (Stars Redeemed)
Awards:Starbucks:Earned -95 SB ; ## Ultimately I want this auto calculated. ##
Awards:Starbucks:Redeemed 8.00 USD @@ 120.00 SB
Awards:Starbucks:Balance
at this point this command give me the following (accurate) balance: $ ledger -f .\Awards.dat -w bal awards -V --empty --flat
0 Awards:Starbucks:Balance
-120.0 SB Awards:Starbucks:Earned
120.0 SB Awards:Starbucks:Redeemed
when I change the last transaction to
2017-01-03 * Starbucks (Stars Redeemed)
Awards:Starbucks:Redeemed 8.00 USD @@ 120.00 SB
Awards:Starbucks:Balance
and add
2017-01-03 * Starbucks (Stars Redeemed)
Awards:Starbucks:Earned
Awards:Starbucks:Balance = 0 SB
I get the following balance:
$ ledger -f .\Awards.dat -w bal awards -V --empty --flat
25.0 SB Awards:Starbucks:Balance
-145.0 SB Awards:Starbucks:Earned
120.0 SB Awards:Starbucks:Redeemed
The question I have is why isn't Awards:Starbucks:Balance = 0 SB? Isn't that what the balance assertion is supposed to insure? And if it does, then shouldn't it also set the last Awards:Starbucks:Earned posting to -95 SB and ultimately resulted in the same balance of
0 Awards:Starbucks:Balance
-120.0 SB Awards:Starbucks:Earned
120.0 SB Awards:Starbucks:Redeemed
Hope that made sense. Thank.
