Disable Keyboard Input

Former Member — Mon, 09 Sep 2013 06:19:01 GMT

I am using a RF hand held device in WM Module, in which there is a requirement that one can scan number using RF Gun should displayed on the input field (i.e. for Material Number), but he can not enter the value in the input field manually through RF Key pad... i.e. the value should only come from the scanner and not from the keyboard... and simultaneously he can enter field value from his Laptop Key board.

what can be done???

Hi,

I think making the field 'DISPLAY' only should achieve the functionality. The PAI event should populate the display after the read and as its Display Only Keyboard input would be disabled.

Cheers,

Hi,

I think the SAPGui can't distinct between the keyboard input and the RF key pad. It's the input method .. that's all. But Former Member have a good idea with the field. Set the field like a password ********* the user will not appreciate to enter a value without see the result, for the RF key pad it's not a problem ...

Hi Krupa,

As far as i know we cannot disable RF keyboard and enable Laptop Keyboard at the same time.

What you can do put a radio button on the screen as:

Take input from:

RF gun
Laptop Keyboard

Below this will be the input field. When the 'RF gun' radiobutton is picked, disable the text field and when 'Laptop Keyboard' radiobutton is selected, enable it.

Even so, i do not get the point in disabling RF keypad when Laptop Keyboard is on as the chances of error on a keyboard are same as that on a RF keypad when entered manually.

Hi,

I gone a bit confused You said

one can scan number using RF Gun should displayed on the input field (i.e. for Material Number), but he can not enter the value in the input field manually through RF Key pad... i.e. the value should only come from the scanner and not from the keyboard..

So you were referring to a field in the screen that shows the scanned number if so how come making a screen field display only impact scanning.

Hi Krupa,

Based on the screen-size (RF will have one and Keyboard Input will have another)-if the entry has been made through RF-Scan, then gray out the area-and if the user tries using RF keyboard-note the number of strokes (don't allow anything greater than 1- give an message and when user okays it-clear his input). In case of Keyboard Entry from say the Desktop-allow entry based on the screen-size. Do you think this will resolve your issue?. Thanks.
