Creating a List of Values Read and Written by a Pipeline

Each component in a pipeline reads values from the order form, performs its function, and then writes values to the order form. Components that run later in the pipeline often read values that previous components have written to the order form. When you are modifying a pipeline or creating a new one, it can be helpful to see a list of the values that each component reads and writes so that you can ensure that the necessary values are present at each point in the pipeline.

With the Pipeline Editor, you can create a text file that lists each component of a pipeline in the order in which it is run. The text file lists all of the components run by the pipeline, including the required components. (The required component always runs last in a stage.) For each component, the file lists the following information:

Input values (values read)
Output values (values written)
Context values (values read from the PipeContextDictionary object, which is passed as a parameter to the Execute method of the pipeline object)

To create a list of all values read and written by a pipeline

Click Start, point to Programs, point to Microsoft Commerce Server 2002, and then click Pipeline Editor.
On the File menu, click Open, and then select the pipeline that contains the values you want to appear on your list.
On the File menu, click Save Values Read & Written.
In the Save as dialog box, specify a location and a file name for the text file, and then click Save.

The Pipeline Editor saves the file and opens it in Microsoft Notepad.
