This relates to the override rules in fund and the different approaches to encumbrance and expenditure. Whereas over encumbrance is handled as a percentage of allocation, the over expenditure is handled as an absolute amount. This make it hard for a budget manager to determine the level of over expenditureas on one hand you are dealing with relative values and on the other absolute.

We'd like to see the option to set over encumbrance or over expenditure as either an absolute amount or a percentage.
