Determining Output Conditions 
Use
You use output conditions to suppress processing of individual nodes or entire subtrees in the tree structure.
Prerequisites
A node exists for which you want to determine a condition. The node must offer the Conditions tab. This applies to most
node types.
Procedure
Select the Conditions tab of the node.
In the Output conditions box you can enter for each line a condition with two operands. An operand can be a
field (in the Comparison value column as well) or a value (in the Field name column as well).

Enter fields without enclosing ampersands ('&').
To select the comparison operator, choose the pushbutton between the two columns.
By default, the system evaluates the conditions in the lines using a logical
AND
. To use a logical
OR
, position the cursor on the desired line and choose
Insert OR (
).
Use the local check to check your output condition.
If desired, link the output conditions to output events of pages and windows. To do this, use the and additional event box.
Result
If the condition is true, the system processes the node. Whether it also processes the successor nodes may depend on other conditions in these nodes. If the condition is false, the system ignores this node and all
successor nodes.
