Tolerance 3.60

Hello, Has anyone implemented Tolerances in the 3.60 US version of Attain? I have tried - but ran into an issue: The Payment Tolerance Warning option is not on the G/L setup {Application} tab. I did Design, and still could not find it as an option to put on the tab. I only know this Payment Tolerance Warning is suppose to exist because I have a document from Navision that talks about this field, plus there is a picture of this field. Thanks for your help
