To easily find inventory in MYOB it is necessary to establish an understandable mnemonic system for labelling the item numbers. E.g. each grouping would be represented by a prefix letter and then further detail. The numbering needs to be in a logical manner, e.g. like something you would look up in a filing cabinet.
A famous mnemonic is Richard Of York Gave Battle In Vain which represents Red, Orange, Yellow, Green, Blue, Indigo, Violet the colours or a rainbow
