If you run a P&L with multiple columns that include prior period data, and the total of that row equals $0, the report will not run unless you check the box that says "include zero line items." The report should also look for data in the columns that make up the total, not just the total. See attached for sample. The highlighted row will only appear if the "include zero line items" box is checked and that results in including a bunch of line items that are all $0, which we don't want. We only want them if there is data in the columns and shouldn't have to run the report this way to get it.
