Find two item codes, inspect their named captures and preview a replacement without changing the source. This is isolated practice with invented records. Nothing is uploaded or written into a live system.
Read these instructions on any device. Watch or practise a chapter on a desktop or laptop, with a desktop or mobile application layout. Demonstrations use sample data and simulated scanners.
