Problem in executing the adobe form

Hi,

Using the SFP tcode i have createda an interface and a form for that interface.

i have to import parameters from vbap table which i have mapped in the form..there is no problem while executing and activating the form...

but while i am executing the form after passing the values i am getting an exception : SYSTEM ERROR

Meassage ID: FPRUNX

ADS: SOAP Runtime Exception: CSoap Exception Transport.

Are the forms craeted using SFP tcode are Standalone forms i.e. non-interactive forms?
