Hello Perumal A,
You can find a simple document here that describes how to create an Operator Template:
When installing a trial license (need to contact QlikView) or the Standard / Enterprise editions - the QlikView Expressor Connector is installed - this will enable QlikView applications to source data directly from a QVE dataflow and allow you to use the results in that manner.
It is demonstrated here in this video starting at or around 6 min 40 secs - 6:40
Without the trial or paide version - you can write data to .qvx files using the Write QlikView Operator. This is demonstrated in the video above and also here at or around the 11 min mark onward.
Let me know if you need additional assistance.
