Objectives
Enables the system to display SAP application data on selected presentation devices such as
handheld barcode reader.
Decoupling of business logic from the physical presentation of application data on a selected
presentation device.
Enable personalized menus, screens and verification profiles.
Enable flexible and user-friendly screen and flow logic generation and modification.
Receiving resource’s input (e.g. verification/input data, keystroke, logon request) and call the
appropriate service.
Supporting large variety of device sizes, presentation device types and data entry types.
Selecting the appropriate form of data presentation according to the application data, device
capabilities and user preferences.

Field Verifications
Verification is done to reduce process errors.
Verification is a comparison of two values.
Verification value is normally entered via barcode scanning.
Input field is 50 characters long but only one visible.
The system will inform if the verification field did not match the comparison field.
Standard verification fields are:
Storage bin (full field or /CSWM/LAGP-VERIF)
HU
Material (material number or EAN number)
Quantity

confidential
Function Keys
Standard function keys:
Are not displayed in the function key line
F5 = More (Display next pushbutton sequence)
F6 = Clear (Clear input field / Clear all input fields)
F7 = Back (Returns to previous screen / step)
F8 = List (Display possible data for the current field)
F9 = Full message (Display message on separate screen)
Transaction specific function keys:
Are displayed in the function key line
If more than 4 keys the “>” indicator is displayed
Used to trigger “not standard” processes/work.
Each function key should have a shortcut defined (e.g. 01 for F1, 08 for F8).

from another logical transaction)
Defined via IMG Menu EWM Mobile Data Entry Define Steps in Logical Transaction
Step-Flows for logical transactions
defines the business process flow and the corresponding content provider function
modules
only function modules can be used
steps can be defined to be called in foreground or background

Automatic Filling of Fields
The Content Provider is responsible for filling out the appropriate fields with content.
It also handles scenarios where automatic filling of fields is required. Examples:
One HU on the bin
One HU containing the requested material
One batch on a bin, which has to be reported during picking
Assigned picking HU
The application can identify the parameters’ type to specify if the field should be open or
closed for input.
The presentation management is responsible for displaying the fields and values by
the required type (i.e. close/open/invisible) as determined by the content provider
