As your question is a very specific one on PI Web Services I have asked our developers to chime in here. We will get back to you shortly. Thanks!
Hi Rashmi -
You cannot have multiple endpoints all pointing to the same PITimeSeries.svc. If you want multiple, concurrent endpoints all running IPITimeSeries, you have to copy the .svc file and rename it. Each copy will access the same assembly and provide the same service, but the different names result in different physical endpoints.
Thank you for submitting your question,
