My require ment is : i have a hardcopy prints invoices( In Encrypted format)  with barcode fromat....for this i developed the dailog screen to insert scanned invoices into Z table.....So, to scan invoices i created the screen field with char40.....& i am placing the cursor on that field & scanning it's scnned correctly and updating in table successfully....

So the problem is ,there is a chance to user can copy the scanned content & saved in othe sources like notepad & after that he copied the content from other source & entering into my screen field ...it will allow to furthe procedure.....

so now i want to restrict to enter the content manually ,  allow to scan through barcode reader.......

Is there any possibility ...?   Plaese help me it's an important for me ..............

In the dynpro definition and PBO define the field as active, input, output and invisible. Like passwords field, user input will be masked by asterisks. Read documentation  like Setting Attributes Dynamically or navigate from MODIFY SCREEN help on Abap source/F1 to find it.

Hi Giuseppi,

Thank u for ur reply.....

i tried what you said ....even in this case also it's allowing to user manual entry.......copy from other source.....

I want restrict the  content enter manually in this field ,..only through scanner read content only i have to allow .....any identification for data entered by scanner in SAP....

Please help me.......

Thanks & Regards,

Subba.

AFAIK that should not be possible,

• Scanner basically only emulate keyboards, so if the field can not be input by keyboard... no input from scanner. 
• Notepad should be able to read scanner which emulate keyboard too so you would have serious problem to disallow that....
• User can always photocopy an original with your "encrypted" code and use the copy as long as they want (if the code is readable by a bar code reader, it should be easily copied...)
  

Else you have to install/use another application on front end to input from scanner like some security devices. (But then going outside of Abap development space)

Hi Raymond,

To resolve this issue any other solution , i have one more doubt if iadd special character '#' in barcode print,while scanning it will read or not & if i scanned same in notepad waht will happen?....

Regards,

Suba.

[RaymondGiuseppi]

Well, you could try, but not much hope, as SAPGUI use Microsoft Visual Studio routines so same as office or many windows tools, so will have same behavior. Also don't use # but an actual not-displayable char.

As i already wrote, did you search for Barcode Reader AddOn ?

hi ,

for doing it,

in attributes window, use the parameters like invisible and asterisk for making it as a password field..

so that your contents ll have security..

hi,

i tried a lot, I think its not possible with the codes..

better this screen setting is the only way of doing it..

check input field and output field then input recommended, and check the field.

up to my knowledge. this is the way.

thanks,

Hi,

  See the link

http://scn.sap.com/thread/1688977

you can try by first checking whether the bar code scnanner is attach to com port or not, and accept the data from comm port only as you  will attach the scanner to your com port.

This is not possible.  Scanner places the value only to the visible area and we cannot differentiate if it was the scanner or the user who did the entry.

Hi kesavdas,

finally i understood ,no possible for identification for getting data from scanner or enter by keyboard in ABAP...........right...........

Any other way to resolve this issue from other sources to SAp........

Thanks .
