Add pop up window w/out programming objects

Wouldn't it be great to add a window to your custom transactions in SAP similar to Purchase Order Create (ME21N) "Document Overview On"?

It is very easy to add this window and impress your users at the same time.

You can program it in the user command area of your transaction so that it dynamically pops up when the user clicks on a button... the user can easily close it also.

Use this window to show help for your transaction, link to html, ... the possibilites are endless!

This can also be used on transactions that use ABAP custom containers.
