Enter external procedure initialization properties on the Initialization Properties tab of the Edit Transformations dialog box. The tab displays different fields, depending on whether the external procedure is COM-style or Informatica-style.
COM-style External Procedure transformations contain the following fields on the Initialization Properties tab:
Programmatic Identifier for Class Factory.
Enter the programmatic identifier of the class factory.
Constructor.
Specify the method of the class factory that creates the EP object.
You can enter an unlimited number of initialization properties to pass to the Constructor method for both COM-style and Informatica-style External Procedure transformations.
To add a new initialization property, click the Add button. Enter the name of the parameter in the Property column and enter the value of the parameter in the Value column. For example, you can enter the following parameters:
Parameter
Value
Param1
abc
Param2
100
Param3
3.17
You must create a one-to-one relation between the initialization properties you define in the Designer and the input parameters of the class factory constructor method. For example, if the constructor has
n
parameters with the last parameter being the output parameter that receives the initialized object, you must define
n – 1
initialization properties in the Designer, one for each input parameter in the constructor method.
You can also use process variables in initialization properties.
