SICF Service not available in Production

Hi Experts,

I have created a Webdynpro application and I have moved it to quality and Production systems respectivelly.

In development and quality system it is working fine, but the same application in production gives a runtime error. It is showing SICF service is not available.

I have checked in SICF Tcode, but the service for the particular Webdynpro application is not available.

How can I resolve this issue.

Thanks,

Pradeep
