Default Expression for Demantra Series!

Hi All

We were analyzing values of few series in demantra demand management and it was not coming as expected. We understand that it may be becoz of the server or client expression defined for these series.

Although these expressions can be changed as per requirement, is there a default value of expression for these default series? Is there a documentation available somewhere which explains each client expression behind default demantra series? Or these demantra series come without any expressions and everything needs to be customized at the time of initial installation?

Thanks

Roger
