Item Name	Description
Behavior	This is always set to Accept, meaning that if the logical expression below evaluates to true, the message will be accepted.
Field	The message field or expression to test.
Condition	Determines how to test the Field set above. The following conditions are supported: Exists: Returns true if the length of the field is greater than 0. Not Exist: Returns true if the length of the field is 0. Equals: If the Values table is empty, returns true if the field is equal to an empty string. If the Values table is not empty, returns true if the field matches any of the values in the Values table below. Not Equal: If the Values table is empty, returns true if the field is not equal to an empty string. If the Values table is not empty, returns true if the field matches none of the values in the Values table below. Contains: Returns true if the field contains any of the values in the Values table below. Not Contain: Returns true if the field contains none of the values in the Values table below.
Values	A table of expressions that may be used in conjunction with the Condition to test the given field and decide whether or not to filter the message.

Iterator Filter Rule

This is a special type of rule that allows you to decide whether to filter a message or not by iterating through an array or list of XML nodes. The child rules underneath the Iterator determine the accept/filter behavior of the overall rule. For additional information, see Working With Iterators. Item Name Description Iterate On The element to iterate on. This may be a list of E4X XML nodes, or a Java / JavaScript array. Index Variable The index variable to use for each iteration. Accept Message If Determines how to logically combine each iteration into the overall accept / filter behavior. At Least One: If the logical combination of the child rules returns true for at least one of the iterations, the overall Iterator behavior will be to accept the message. All: If the logical combination of the child rules returns true for all of the iterations, the overall Iterator behavior will be to accept the message. Break Early If this is enabled, the iterator loop will terminate as quickly as p

Destination Set Filter Transformer Step

Destination Set Filtering is a powerful feature of the source transformer that allows you to decide in advance which destinations to exclude from message processing. Using each individual destination's filter to control where a message goes is still a valid workflow, but when you have many destinations all with mutually exclusive filters, the performance of the channel can be affected because message data will be stored to the database for each destination connector. Also filtered connector messages can clutter up the message browser, making it harder to find what you are looking for. The advantage to using Destination Set Filtering in this case is that filtered destinations will not have any message data stored, and will not show up in the message browser. This can greatly increase message throughput. Destination Set Filtering can be done manually with JavaScript (look at DestinationSet in the User API) . However this step allows easier access to the feature without having to write an

Filter Tasks

The following context-specific tasks are available throughout the Edit Filter View: Task Icon Task Name Description Add New Rule Adds a new filter rule to the table. If an Iterator rule or any rule that is a child of an Iterator is currently selected, the new rule is placed at the end of the children of the most immediate parent Iterator. Otherwise, the new rule is placed at the very end of the list at the bottom of the table. Delete Rule Removes the currently selected rule from the table. If an Iterator rule is deleted, all of its children are also deleted. Assign To Iterator Adds the selected rule to a new or existing Iterator. For additional information, see Working With Iterators. Remove From Iterator Removes the selected rule from its current Iterator. For additional information, see Working With Iterators. Import Filter Imports a filter from an XML file. You can choose to completely replace the current filter or simply append the rules to the current table. For additional informa

Rule/Step Table

The table in the top half of the Edit Filter / Transformer Views shows all the rules/steps you currently have configured. If you have Iterators, the elements are organized into a tree-table with the children underneath each Iterator. Column Description Enabled Determines whether the rule/step is currently enabled. When disabled, rules/steps are not executed at all, and act as if they were never there in the first place. For filters, this could change behavior as it follows the AND/OR order of operations. When all rules in a filter are disabled, the filter acts as if no rules exist, and is not executed at all. # This is the sequence number of the rule / step, starting at 0 for the first one. For child elements underneath an Iterator, this will be multiple numbers separated by a dash, to indicate the child index of each depth level. Name This is the name of the rule / step. If the type of rule / step allows user editing, you can double-click the cell to edit the name. For filter rules, y

Message Builder Transformer Step

This step extracts data from a field in the message (or an expression) and maps it into a specific field in the inbound or outbound message. This can be used to simply modify a field in the inbound message, copy a field from one place to another, or map data from the inbound message to the outbound message. Item Name Description Message Segment The field/location in the inbound or outbound message to place the value into. Mapping The value to place into the given message segment. This may be a field from the message, or any JavaScript expression. Default Value If the Mapping is not found or evaluates to an empty string, this value / expression is used instead. String Replacement This table allows you to perform replacements on the value before it gets inserted. Regular Expression: A Java-style regular expression to test against the value. This will implicitly set the global regex flag. Replace With: The value to replace any matched regions with. Parent topic: Transformer Step Propertie

Search Trigger Values

You can search for specified values in conditions and parameters for selected types of triggers in the currently open template. The search values can include fields, variables, functions, characters, or other values. You can then select a trigger from the search results for editing. Do one of the following: To automatically populate the search value with a specific template field, either: Right-click the field, and then select Find in Triggers from the menu. Select the field, and then select Find in triggers on the Main toolbar. To manually enter the search value, select Find in Triggers on the Triggers window. The Find In Triggers window opens. If applicable, the search value box displays the selected field. The window contains check boxes for commonly used triggers and for conditions. The Conditions and Assign Field Value check boxes are selected by default. If the search value is blank or you want to change it, enter the value in the input box.
