Source Section

Source Section

The Source section contains the input parameters for the rule. You can configure a maximum of 10 input parameters.
The following table describes the properties that you can configure in the Source section:
Property
Required/
Optional
Description
Model
Required
Source model defined on the Models worksheet that includes the source column that you want to transform with the rule.
Parameter Name
Required
Name of the input parameter. The PowerCenter Repository Service assigns this value to a Java transformation input port.
Parameter Description
Optional
Description of the input parameter. The PowerCenter Repository Service does not import this value.
Parameter Datatype
Required
Datatype of the input parameter. Select one of the following options:
  • Datatype valid for the selected source model. The PowerCenter Repository Service assigns the value to the datatype of the Java transformation input port.
  • Domain name defined on the Domains worksheet. The PowerCenter Repository Service assigns the datatype, length, and scale defined on the Domains worksheet to the Java transformation input port.
Parameter Length
Required
Length of the input parameter. The PowerCenter Repository Service assigns this value to the precision of the Java transformation input port.
Parameter Scale
Required
Scale of the input parameter. The PowerCenter Repository Service assigns this value to the scale of the Java transformation input port.
Parameter Value
Optional
Value that the input parameter must have to meet the rule condition. If you selected a domain name for the datatype, the mapping specification displays a list of all possible domain values defined on the Enumerations worksheet.
If blank, all values of the input parameter meet the rule condition.
The value can contain any of the following:
  • Constant. Enter a number or a string value.
  • Simple expression. Enter a comparison operator such as > or < followed by the value to compare. For example: 
    >25
  • Complex expression. Enter a complex expression within parentheses. For example: 
    (stateWord.toUpperCase().startsWith("CALI"))
The expression must include Java supported operators. The PowerCenter Repository Service uses this value to create an if statement in the Java code of the Java transformation.
