Warehouse tasks can be executed in a warehouse either via paper-based working or via working with a mobile device. Paper-based means that the instruction is printed (like a pick list): the warehouse worker marks on the piece of paper what they have done and also any deviations if needed. Someone later enters this information in the SAP S/4HANA system. This way of working has certain limitations and disadvantages. For example: the delay between the actual processing of the materials and the entering of the information in the system might make it impossible to react timely to issues. If a worker manually selects another bin than instructed (for whatever reason) and notes this information on the piece of paper, then this is not known to others until the information is entered in the system. Other people executing other processes could thus be triggered to start their processing based on wrong information.
When working with a mobile device, the system can react directly to information entered by the user, so, for example, when the originally assigned bin cannot be used, the system can determine the next available bin. It is also a way to avoid errors which can happen when transferring the information from paper into the system. There are also special processes in SAP EWM that are only available when the users work with mobile devices.
Types of Mobile Devices
Note
In the following video, Peter explains some characteristics of working with mobile devices. The video also shows some examples:Note
Pick-by-voice means, that the user wears a headset (instead of looking on a display) and the task-related information is then audible. Confirmations are done via speech input.
