An arrangement and a method are provided for detecting and controlling piece goods (2) having a code, preferably of piece goods commissioned in a commissioning system for a complete commissioning order. The piece goods of a quantity, preferably a commissioning order, are singulated and centered on a transport route (3) and fed through a scanning device (15), and are identified as actual data in the scanning device (15) by reading the code of the piece goods (2). This is compared or captured to target data of the piece goods quantity. The piece goods are separated out if the target data do not match the actual data. A first transport route (3) has a V-shaped cross-section, the one V-arm thereof being a driven piece goods transport element (5) preferably a drive recirculating conveyor belt, and the other V-arm thereof being a stationary piece goods sliding element (6), preferably a sheet metal slide.
