Hi

In a receive function you can specify source, dest,
openness, etc. Is there any way of changing or clearing
any of these values in the preprocessor? Even a right
hacky way of doing it might help.

Thanks!

Consider the followin my very best guess, as I am not sure how BizTalk
works internally on this issue.

Anyway, as I see it, a Receive Function will put the document through
the preprocessor and look at the result. It will then determine which
channel(s) the document is to go through. It will then put the
document into the Work-queue with this information and any BizTalk
Server can then pick up the document and process it.

Now to your question; Can you change the details of the Receive
Function in the preprocessor? I am not sure. It makes sense that you
can do it, since you are in code. But can you change the settings of a
receive function that is active? I don't know. And besides that, what
will happen if two documents are being processed in the preprocessor
at the same time and they try to change different settings on the
receife function? This will probably give som unexpected behaviour. So
in short, I definately wouldn't go that way... and I really can not
see why you would want to do it anyway :-)

Hope this helped... just a little bit?

well, sort of.

I have a preprocessor that performs some very complex manipulations on a
very large document, creating hundreds or even thousands of smaller
documents, each of which is submitted BY THE PREPROCESSOR to Biztalk.  When
I am done with the work, I return a "job control" document to Biztalk which
is not mapped, but is used by an AIC (a long story).

The point is that the preprocessor can take the input file, do somethings to
it, and call Submit on the data.  As long as the preprocessor returns
SOMETHING to Biztalk, it does not have to be the document it read from the
hard drive or the queue.  It can be an XML file with some tracking content,
or something like that.

I hope this helps.

Thanks Jan. The reason we want to do it is that sometimes
based on the content of the message we want to change the
openness from "open destination" (as defined by the
receive function) to "not open", in order that different
channel/port matching occurs. Any ideas?

As an alternative, set up a receive function to submit to a dummy channel.
Then have the preprocess contain the logic for
(a) determining if the document is known, and should go to a specific
channel, or
(b) submitting the document with an open destination to allow Biztalk to
select a channel.

The preprocesser can return a dummy XML that a dummy channel sends to an
auditing port.

This would do what you want.
