Example 3: Opening the Assembly Editor and viewing the issues

Tom opens the Assembly Editor for the Hierarchical Data stage to design a job that uses the HTTP methods in the REST web service.

About this task

Tom adds the first REST step to search for a term that has an incorrect definition in the business glossary. Then, Tom adds one XML Parser step to parse the output of the REST step to get the resource URI of the term. Finally, Tom adds one more REST step between the XML Parser step and the Output step to correct the term definition.

Procedure

  1. Double-click the Hierarchical Data stage, and then click Edit assembly.
  2. Click Palette, and then double-click the REST step to add it to the outline. Because the REST step is the first step that you added to the assembly, the step is added between the Input step and the Output step.
  3. In the outline, error icons (red exclamation marks) are shown beside the REST step and the Output step. The error icons indicate that you must address one or more issues in that step.
  4. To view the issues list, click View All. The links and columns that you defined on the httpGET and httpPUT links are listed as errors because the hierarchical structure of the assembly is not mapped to a relational structure. You can correct these errors when you create mappings in the Output step.
  5. Close the issues list.
