This section describes possible scenarios for interfacing mobile data entry systems to SAP R/3 and explains the related business principles. The collection of scenarios described is not complete and should be regarded merely as a series of possible interfaces illustrating typical applications. In contrast to the LSR interface, the mobile data entry interface is module-neutral, i.e. interfaces to the Warehouse Management system as well as the Inventory Management and Sales and Distribution modules are also discussed.

The interfaces described in this section are examples of implementing mobile data entry devices. Each individual case must be analyzed in order to determine which applications are possible and practical.

All standard IDocs of the WM-LSR and MM-MOB interfaces can, in principle, be used for mobile data entry applications.

Mobile functions can also be used as an extension of the logistics chain using a control computer to enable paper-free stock placement and removal.

Refer to the appropriate descriptions of the individual IDocs for details on their technical structure and sending and receiving them.
