Entering the Data Breakpoint Condition

When you create a data condition, you enter a global parameter or a parameter for a single transformation. You have different options depending on the selected instance and the type of condition you create.

Use the following syntax when you evaluate a transformation against a port or constant value:

<port> <operator> <type> <value>

Use the following syntax when you check for null and default values, either globally or in a transformation:

<port> <operator>

For a single transformation, you can enter multiple conditions within one breakpoint if you want the Debugger to pause when all the conditions are true. You can also enter multiple breakpoints for a single transformation if you want the Debugger to pause when at least one condition is true.

The following figure shows multiple conditions within a single breakpoint:

The breakpoint contains the following conditions: IN_AVG_PRICE >= [13000] AND OUT_AVG_PROFIT = 10000.

In this example, the Debugger pauses when both conditions are true.

The following figure shows multiple breakpoints within a single transformation:

The condition for Breakpoint 1 is IN_AVG_PRICE >= [13000]. The condition for Breakpoint 2 is OUT_AVG_PROFIT = 10000.

In this example, the Debugger pauses when either condition is true.

The following table describes the condition parameters for transformation and global data breakpoints:

Parameter	Transformation Options	Global Options
Port	Choose port name, <<ROW-ID>>, <<ROW-TYPE>>, or <<ANY-PORT>>.	<ANY-PORT>. You can evaluate this condition against each port in each transformation and mapplet.
Operator	<, <=, =, >, >=, !=, ISNULL, ISDEFAULT.	ISNULL, ISDEFAULT.
Type	Constant, Port. Evaluate against a constant value or another port in the transformation.	Not available.
Value	Enter the value or select the port name.	Not available.
