Internally they are currently represented as: income=400,expenses=200, loan=-200, savings=100. As Phil reports; income-expenses-assets+liability = 0. The more consistent approach is: income=-400, expense=200, loan=200, savings=100. We can't fix this for 3.x as this is a data format change.

It will offer scan the budget amounts, make an educated guess at the sign-reversal strategy in use, heavily biased towards using credit-accounts. Then sets a feature flag to trigger the newer code path and prevent writing datafile by versions prior to 3.8, and prompt the user to recheck all budgets. If the user elects to delay the sign conversion, the budget will be read only until the conversion is run. *But all of this will be stalled until the current budget viewer is thoroughly debugged.* _______________________________________________ gnucash-devel mailing list gnucash-devel@gnucash.org https://lists.gnucash.org/mailman/listinfo/gnucash-devel
