I got access denied while integrating WebDynpro appl into EP

Hi all,

I have created one appl in WD that can access details from R/3. Whenever I run the appl, the data is automatically populated from R/3 into dropdown list. It is working fine in my NWDS.

I have integrated this appl in to Enterprise Portal. Now when i execute that appl, I am getting

<b>'Access Denied error'.</b> (The data is not poulating into my dropdown list).

But I have integrated the FlightList appl, into Enterprise Portal, which is working fine.

Is there any settings/configurations needs to be done before integrating my appl into EP?

Thanks&regards,

Ganesh
