Guidelines for Writing Expressions and Filters
When you write expressions and filters, keep the following points in mind:
*Operators, variable names, and strings are case sensitive.
*White space between the tokens of an expression is ignored.
*Some syntax that is valid on the Integration Server is not valid on the Broker. Broker saves the filter with the document type subscription on the Broker only if the syntax is valid. Filters are always saved on the Integration Server. For more information about using trigger filters when Broker is the messaging provider, see Creating Filters for Use with webMethods Broker .
For a list and an example of syntax that prevents syntax from being saved on the Broker, see Rules for Use of Expression Syntax with the Broker.
