Execute Standard SAP Transaction from BSP using dynamically created shortcut
The ABAP/HTML code below shows you how to execute a standard SAP transaction from your BSP application, the example is built
around calling tcode PA20 but this is just for demonstration purposes and you can use whichever transaction you want.
If you have not created a BSP before you will need to look the following example of creating a simple BSP application just to get an
understanding of the basic components. You can then use the information below to build the BSP.
