Hi!

For webdynpro.

Place the cursor in your inputfield:

Method (standard) WDDOMODIFYVIEW of your view

*Data declarations for VIEW
  data: lv_v_elem type ref to if_wd_view_element
    lv_v_elem = view->get_element( 'YOURFIELD' ).
  if lv_v_elem is bound.
    view->request_focus_on_view_elem( lv_v_elem ).
  endif.

Handle ENTER of your input-field.

In layout of your view - select your inputfield - in properties you have Events onENTER - Here you can create an event that respond to your ENTER command.

Within your method...

Get the value from your inputfield (the data that was scanned)

lo_el_context = wd_context->get_element(  ).

* get single attribute
  lo_el_context->get_attribute(
    EXPORTING
      name =  `YOURFIELD`
    IMPORTING
      value = lv_yourvariable ).

Insert the code you need to handle your scanned id...

Set data of your inputfield to space...so you can scan again...

lo_el_context->set_attribute(
    EXPORTING
      value = ''
      name =  'YOURFIELD' ) .

Hope this helps...

Hi,

Actually I have seen your thread on SDN regarding reagarding usage of BARCODE SCANNER and fetch data on webdynpro ABAP. I am very sorry to give you trouble but if you can help me out with the same scenario I have.

Scenario: I have Table Control having 3 column on webdynpro ABAP . When i will scan the product,

material code should be in first column,

material description should come on 2nd column and

3rd column will have quantity which i need to enter manually.

so by reading your thread i can understand that in WDDOMODIFYVIEW , i have to set the cursor on input field of the table first of all. and than on input field of the table i have to create ONENTER event handler method where i have to get the value which is being scanned( in my case it would be barcode which is being scanned ) and proccess it into database and fetch relevant material code and than set the same input field with that code if i m not wrong.

But now my question is how to attach barcode with perticular material code in SAP ? and I heard its something EAN field in material master but i m not getting it how.?

Second thing do we need any more configuration to make this scanning functionality worked or its job of barcode vendor or something else?

Please Please let me help in this scenario. I will be grateful if you can help me.

Thanks,

Hi

The only thing I did in Webdynpro was to make sure that the cursor stays in my input-field AND to have an action-event when pressing ENTER on the input field.

So when I start the web-application...cursor is positioned...and then I scan the barcode....this is entered in the my web app..

Then I beliave you need a specific application for Your scanner-product. In my product I can configure it to send and ENTER after each scanned code (this is good since I have an ON-ENTER action in my web dynpro)

Hi

Yes this should be possible.

I have a reader connected via usb.

A Twedge-app then convert the read ID/barcode into keystrokes+autoENTER that is entered into an inputfield in your webdynpro.In webdynpro you than can handle event ON-ENTER and append to ALV-table or anything you wish.

Best reg
