Simulate Copy-From Button Click on Delivery Document

Hi Friends,

How can I 'programmatically' click on Copy From button, and then select the Sales Order?

(I could get a forum post to capture the Copy From button click in the delivery document, but I want to do clicking also programmatically)

I could click on the Copy-From button programmatically.

After that, till I manually click on "Sales Order", control is not returned to the program (It acts similar to a message box:( )

Do you know any ways to acheive it?

Thanks.

Regards,

Geetha
