SAP Console Code

Hi,

I have posted this in RFID and ABAP Programming areas, so apologies to anyone who comes across it twice. Simple question, I hope.

When the user scans an 'RFID Product' a custom screen for, say, creating a goods receipt is opened. How does this happen? Where is the setting that tells the device to open a certain transaction and pre-populate fields?

Thanks.

Hi kroc,

1. It will work just like a barcode scanner.

2. barcode scanner works just like

a keyboard/typewriter.

EG.

3. If we open a notepad,

and scan a barcode,

then the barcode will TRANSMIT CHARACTER DATA

(just like keyboard),

to the computer thru attached wire/usb etc,

and the Characters will

get KEYED IN (automatically)

in the notepad.

4. So if we place the cursor in notepad,

or any other screen, or sap r/3 transaction field,

then the characters will get KEYED IN

on the CURSOR PLACE,

(just as if someone has TYPED in the data)

5. In the sequnce of characteres,

there is also sometimes a TAB character,

which is synonmmous to TAB,

and the cursor goes to the next field.

Hi, it is my understanding that the application must be running already with an input field on the screen which the scanner device will fill with data when scanned.

Amit/Rich,

thanks for the amazingly quick reply. That's exactly what I wanted to hear. So, it seems like the solution is the screen will default to the doc number field and if we want a few fields pre-populated we just have TABS in the Tag.

Thanks again.

You can handle this a few ways, you can build intelligence into the barcode itself, or let the system work for you. For example, if your barcode has the document number and you need other things that are associated with that document number to show on the screen, simply allow the user to scan the document number into an input field on the screen, user will hit enter(or auto-enter can be configured) and the PAI will fire, here you can retrieve the relevant data from the database and present back to the user on the screen.
