Hi ,
The Message coming to biztalk is consists of content and
context. Content is Data i.e body part of xml and Context
is the Information Written by Various Biztalk components at
the time of Pipelining and by adapters. for security resons
biztalk is build like that it can see only the context
properties. It cannot see the content properties. so in
order to see the elemennts of xml by biztalk, the elements
must be moved(promoted) from Content to Context. This is
called Promoting.It is done at Receive ports, And Demoting
also Must be done at the send ports.
Distingushed properties are like Call by values and these
are light weight. and these are exposed only to
Orchestration and hence it is used only in Orchestration
Solution. for this element limit is unlimited
Promoted properties are like call by references and these
are more weight. and these are exposed by all the
components of biztalk.element limit is upto 255.
when we add the promoted property it creates a prpoerty
schema . it have only the elements which are promoted and
it have No Root and the one default element is property1.
It is having no importance. we can delete it or we can kept
it like that only
Normally we promote the properties on the schema, but
logically they are done at disassemble stage of receive
pipeline
Distiguished fields are used in only Orchestration soultions
(i.e solutions have Orchestrations)
Promoted fields can be used in Orchestration solutions and
Messaging Solutions(Solutions With Out Having
Orchestrations)
Distinguished properties are Used Mostly in EAI Appllication
(i.e Applications in same organisations)
Property Promotions are used mostly in B2B Applications.
(i.e Application across different organisations for
different purpose.
If any Mistakes are there Please Notify me.

In the dynamic send port actually we have to give the require destination details i.e, provided by client, but my question is how to get that particular address from where and where it is stored in biztalk?
