TouchScreen for SAP ERP

Using GuiXT/Input Assistant and the Viewer you can easily enable touch screen operation

To use SAP ERP appropriately via a touch screen you need

• to provide a corresponding keyboard for entry in an entry field or a long text
• to provide a list for navigation possibilities
• to provide large push buttons to call up functions (at least 70x70 pix)
• instead of selection guide F4, to provide access to values as images (70x70)

1. Keyboards

The keyboard is called up by clicking on an icon (at least 70x70 Pix).

The command line required for this is :

Image F[VBAK-VKORG]+(-3.0,19) "Change.gif" Input="U[KEYBOARD]:NUM;U[FIELDNAME]:VBAK-VKORG;OK:process=keyboard.txt" -NoStretch

In so doing, care should be taken that the type of keyboard is assigned to parameter U[KEYBOARD] NUM = numeric keyboard CHAR = QWERTZ keyboard. The field name is assigned with U[FIELDNAME].

1.1 QWERTZ-keyboard

1.2 Num keyboard

2. Navigation in lists

Cursor control is achieved with the following commands :

Image (0,1) (3,8) "Down.gif" Input="X[Grid1]+(15,0):<DOWN>" Image (0,10) (3,18) "Up.gif" Input="X[Grid1]+(15,0):<UP>" Image (0,20) (3,28) "Next.gif" Input="X[Grid1]+(15,0):<NEXT>" Image (0,30) (3,38) "Prior.gif" Input="X[Grid1]+(15,0):<PRIOR>" Image (0,40) (3,48) "Bottom.gif" Input="X[Grid1]+(15,0):<BOTTOM>" Image (0,50) (3,58) "Top.gif" Input="X[Grid1]+(15,0):<TOP>" Image (0,60) (3,68) "End.gif" Input="X[Grid1]+(15,0):<END>" Image (0,70) (3,78) "Home.gif" Input="X[Grid1]+(15,0):<HOME>"

It should be noted that at least GuiXT Version 2009 Q2 1 is required.

3. Selection button instead of F4

So that the application is simplified, in practice only individual values will be offered rather than complete value help (F4) during touch screen operation.
The selection buttons have been designed with the Image command and the additional TextString= :

Image F[RV45A-TXT_AUART]+(-3.0,38) "Background.jpg" TextString="TA" Textheight="50" Textweight="8" -textcenter Input="U[VALUE]:TA;U[FIELDNAME]:RV45A-TXT_AUART;OK:process=Werte_setzen.txt" Image F[RV45A-TXT_AUART]+(-3.0,51) "Background.jpg" TextString="RE" Textheight="50" Textweight="8" -textcenter Input="U[VALUE]:RE;U[FIELDNAME]:RV45A-TXT_AUART;OK:process=Werte_setzen.txt"
