    2 (x + y) = 2x + 2y

    so NOT (Ship OR Invoice OR Receive) = NOT Ship OR NOT Invoice OR NOT Receive

    %1 is in the manuals, so you should be able to learn that from them.

    I know it can be hard, but step one is to read the manuals. If you don't want to read the books, then find a course and pay to take it.

    Be careful! The associative property for multiplication and addition does not extend in the same way to negation and logical operations. Check out De Morgan's laws (http://en.wikipedia.org/wiki/De_Morgan's_laws) for the correct relationship.

    Yeah, that actually equals NOT Ship AND NOT Invoice AND NOT Receive. The NOT negates everything, and the negative / opposite of OR is AND.

    But yes, you need to read the manuals more carefully, Tony. It's one thing if you are asking the purpose of code in the application, quite another if you are asking basic syntax questions.

    Conditionals, setting filters, array syntax....every one of them is in the application designers guide or the development coursework.

    Don't get discouraged. NAV takes a long time to learn well. Hard work will pay off.
