Procedure

  1. Press Ctrl+S to save your Job.
  2. In the Run tab, click Run to execute the Job.
    In this case, no errors occur, so the Job triggers the second tJava component only.
  3. Double-click the tHMap component to open the Map editor.
  4. Right-click the outputKey element and click Go to Structure Element.
  5. Change the tHMap_1_output structure that opens from Read Only to Editable and then change the Data Type for outputkey to Integer (32). This means that this element can only be an Integer, and since this does not match the input, an error will occur.
  6. In the Run tab, click Run to execute the Job again.
    In this case, the Job still triggers the second tJava component even though there is an error, because the threshold above which an exception should be thrown (thus enabling the downstream components to detect the error) is set as Fatal. However, the third tJava component is also triggered since there is an error in the execution of the map.
  7. In the tHMap component, change the value of the Exception Threshold drop-down list (on the Advanced Settings tab) to Error. This causes an exception to be thrown when the map has a severity of Error or higher.
  8. In the Run tab, click Run to execute the Job for a third time.
    In this case, the Job detects the error and triggers the first tJava component (OnSubjobError).
