Currently the Biztalk Filtering shape Expression editor uses the DNF (Disjun
ctive Normal Form) thus does not allow the developer to put in complex condi
tions in the filter expression.
There are times when CNF forms are better.

Although editing the filtering expression within the odx file directly using
 the text editor builds the project and deploy the complex expression fine. 
There is only one problem, Visual studio will not pickup the change and henc
e we cannot see the modifie
d expression using visual studio.

Questions.

1. What are the options we have when we have to write complex expressions of
 the form (Cond1 || cond2 || cond3 || cond4) && ((cond5 || cond 6 || cond 7|
| cond8) && (cond8 || cond 9)) && cond10. in this case expression needs to b
e converted to the followin
g expression which will be very difficult to maintain (cond4 && cond5 && con
d8 && cond10) ||  (cond4 && cond6 && cond8..)..... all combinations(around 3
2 to 33)

2. The same conditon holds good for send port filtering expression and since
 there is no odx file there is there any place we can edit this expression f
ree hand?
3.Is Microsoft aware of these issues? and are there any work arounds for the
 same.

Thanks

Just want to point out here...

Manually editing the orchestration file is *not* a supported scenario.  If
the designer does not allow you for using CNF, this means CNF is not
supported.

Kind regards,
Christof

CNF is not supported in BTS 2004.

There are times when CNF forms are better.

Although editing the filtering expression within the odx file directly
using the text editor builds the project and deploy the complex expression
fine. There is only one problem, Visual studio will not pickup the change
