Unable to trigger Debug in SRM Web dynpro ABAP through Portal

Hi,

We have some SRM Web dynpro ABAP application deployed on portal.

I am unable to DEBUG the Webdynpro aaplication when it is executed from portal.

I have the same user id and Client for portal as well as SAP GUI.

I had placed a external break point in Code from GUI and executed the same application in Portal. Still the DEBUG screen is not opened.

Please let me know if any other settings are required to enable debugging.

Any pointers to this regard will be appreciated.

Thanks & Regards,

Mayank Agarwal
