Do i need ADS so as to use PDF-Based Print Forms?(Please URGENT)

Hi All ,

I am trying to run the test program FP_TEST_03 (Flight Booking Example) in sa38.

When i run it i select Output Device and Print Preview.

But i cannot see the print form i supposed to see.

I can see this message

Keine gültige HTTP Verbindung: ADS.

Do i need to install ADS?

Generally, could i work with PDF-Based Print Forms without installing ADS?

Please i want a sure answer for this question.

Thank you.

Regards,

Ari
