How to create a QR code and show it in a Smartform

Before running the code given below what should we do?

1. Create a smartform. Follow the steps given below.

   

2. Goto Form Interface and add a new variable under the import tab which holds the name
of the qrcode that we are passing from the driver program[W_NAME  type char20]

    

3. Create a new graphics and as shown below give the name as &W_NAME&. [Dynamic
variable]

       

  4.  Done.

  5. Copy the code below.

  6. Enjoy the emerging technology of qrcode in SAP.

Note : In the program given below I have used a screen 9000. Please do create it before running and also create acustom control in the screen layout and give the name ‘PICTURECONTROL’ to it.
