Guys, I've been trying to create a new invoice print format that can be selected from sales print configuration just below the line 'Print in Simple Format', adding a new line 'Print in Custom Format'. The following is my code: [#Formrint.....] Add:Lines:Before:CustomerSignature:SACustom [#Line:SACustom] Local:Field:Medium Prompt:Logical Field Local:Field:Info:$$String "Print in Custom Format?" Local:Field:Modifies SACustom The line comes alright but I want to add "No" as the default value. Also the logical field should be activated when changed to "Yes" calling the new invoice print format.
