Note: For earlier versions of Warehouse Insight, find the documentation here.

The Designer interface consists of a pre-set number of blocks. Each control/block performs a specific task or encompasses a pre-defined event in the system. Some blocks are used to respond to actions taken by users (e.g., when a barcode is scanned) on the handheld while others are used to initiate actions for the user to respond to (e.g., asking for quantity) while other blocks are there merely to facilitate the application flow (e.g., sending and getting data from Business Central ).

The designer has no pre-determined width or height and can be scrolled indefinitely. However, a good practice to follow when making large applications is to put each starting event in a single row so that finding a specific event requires scrolling horizontally rather than scrolling vertically as well. For simpler applications, a single-screen layout is usually best.
