Managing expenses as positive, reporting as negative
we have a client that manages expenses at GL account level as positive numbers. they rollup the GL accounts to reporting lines (they have multiple GL accounts for salary and report salary on a P&L). the reporting lines are hierarchical (total income and total expenses aggregate to profit before tax). they would like to use Anaplan natural aggregation to sum up their P&L hierarchy. what is the best way to keep the treatment of expense line items as positive while at the same time subtracting expenses from income to get to profit before tax? thanks in advance for any suggestions.
