IS/GM insanely different

Greetings from an epicnoob!

Could anyone tell me why our Income Statements might be different than the Gross Margin reports we get out of Epicor? Shouldn’t the statements and reports be generated from the same data?

I know the IS includes some accounts the GM report does not but even after accounting for the obvious ones the numbers still don’t add up. (Freight for example)

Our IS appears to have a huge difference in Material Costs versus the GM report. The IS also has some other, lesser, differences between labor, burden and subcontract costs.

Being as new to Epicor as I am I really don’t know how to locate where the data is being pulled from for these different reports.

Any help would be greatly appreciated.
