|
* @brief GnuCash Budgets
|
|
*
|
|
* Design decisions:
|
|
*
|
|
* - The budget values that the user enters (and that are stored) for
|
|
* each account are inclusive of any sub-accounts.
|
|
*
|
|
* - Reason: This allows the user to budget an amount for a
|
|
* "parent" account, while tracking (e.g.) expenses with more
|
|
* detail in sub-accounts.
|
|
*
|
|
* - Implication: when reporting budgeted values for parent
|
|
* accounts, just show the stored value, not a sum.
|
|
*
|
|
* - Budget values are always in the account's commodity.
|
|
*
|
|
*
|
|
*
|
|
* Accounts with sub-accounts can have a value budgeted. For those
|
|
* accounts,
|
|
*
|
|
* Option 1: when setting or getting budgeted values, the value is
|
|
* *always* exclusive of sub-account values. Pro: consistent
|
|
* values in all contexts. Con: no summary behavior.
|
|
*
|
|
* Option 2: make setting only for account proper, but always
|
|
* report summaries. Con: value can change as soon as it is
|
|
* entered; forces entry from bottom-up.
|
|
*
|
|
* * Option 3: value is always *inclusive* of sub-accounts, although
|
|
* potentially in a different commodity. Pro: allows top-down
|
|
* entry; no auto value update. Con: ? [ This option was selected. ]
