No it will not be generated by an activity planner service. It will have its
own service I don't know may be encouterSevice or something like that. But
Activity planner is going to make use of Encounters. As you mentioned the
whole world doesn't go by the plan but as far as Health Extension program is
concerned then that is the reality. I mean health workers will be given a
sheet of paper list of names together with house numbers and the kind of
service they are going to provide on the date specified.

Now to the auditing thing, forget for the time being the activity planning
or the community thing. I have seen a 1.4 patient module. When ever you
click on the person icon and new pop up window opens with a list of items to
be populated inluding the name of the person. I think this for me is an
Encounter. A clincian has been waiting for a patient to arrive, a patinet
arrives and the clinican picks a piece of paper/form to register the
incidence - could be death, birth or immunization or generally a treatment.
For me this is an encounter which got shaped dyanamically (for example the
individual identified during the point of care). And just like paper forms
(for recording such an incidence) are printed before hand like a template,
then a dataset (the current one)  will be used as a template to generate a
more advanced and dynamic one called Encounter

The activity planner by no means introduced the Encounter. I don't know may
be I got influenced by OpenMRS, at least on this Encounter thing. That is
how they modeled it - Saptarshi can you comment on this?

Thanks
Abyot.
