Hi,

You can use an iframe in a BSP page to load the external URL.

The process for launching the external URLs should be same as Web Dynpro Transactions. But in this case while defining the URLs in the transaction launcher , you have to select the option for Non BSP URLs & defiine a MAPPED Logsys( In your case the could be any system in which the application exists). Also the URL for Web Dynpro applicatons is sap/bc/webdynpro/sap/Web_Dynpro_Component_Name and is recognized by the target system. In your case you have to build a URL which should be recognized by your target system.

This is how I have launched a ABAP webdynpro transaction. I guess if the URL is correct you can launch other external transactions.

Hi Kavindra,

Even i thought of doing it through Launch transactions, But the requirement is that we have to create a button.

and through that button we have to call the external appln.

thanx though.

I have tried this with a javascript that I place in the.htm file of a view. When I click the button I set a variable in the controller. In the .htm file I check if the variable has been set and output the javascript. The javascript basically does a window.open to the url of the external app. This technique is employed by the web ui for the print preview function.

Hi,

In the code where you defined the button use below sample code

ls_button-on_client_click = 'javascript:window.open ("http://www.google.com","Google","width=750,height=600,resizable=yes");Google.focus()'.
