Thanks for your reply, indeed, as you answered, we run the Web Gui overhere.
If we make our selections in the Web Gui, finally we have an URL. If i copy this URL in a button, the SAP session opens in the transaction we want.
But....... Now here is the tricky part.
How can we make the HTLM coding flexible. How can I use a QV variable in the HTML string? On the internet there is a lot of info around SAP HTML Business, SAP ITS and so on, but how to encrypt this variable ....stays undiscovered (for now)
