Once the conference starts, please come see us at Expo Booth 310. Read on for more information on the two training classes and seven sessions I am presenting or assisting with.

David Meego - Click for blog homepageA recent customization project I was working on using GP Power Tools required the calculation of a square root as part of some number crunching needed to work out material quantities on a Sales Order Processing transaction.
