Looking for field controlling "Don’t show corrections"

SOLVED

Hello everyone,

I have exported data from Sage 50 to Microsoft Access through ODBC. In Sage, whenever we produce reports, for example Project Income, we have an option to check or uncheck show "Corrections". Which field controls for this boolean switch and in which table? I figured it has something to do with the ntype field in tJourEnt table because its function is to show journal entry type but this doesn't account for the whole inclusion/exclusion from reports. Anybody can help with this? Thanks so much.
