Description:
It is sometimes required to create an index or iterator controlled loop in an MDM workflow. To assist in this process, this knowledge article provides a template of how this can be achieved for various scenarios. Each scenario follows the same basic (template) pattern.
It is sometimes required to create an index or iterator controlled loop in an MDM workflow. To assist in this process, this knowledge article provides a template of how this can be achieved for various scenarios. Each scenario follows the same basic (template) pattern.
Issue/Introduction
Creating an index or iterator controlled loop in an MDM workflow.
Resolution
Template Pattern: Creating an index or iterator controlled loop in an MDM workflow is made possible by use of the InterpretCommand activity. The pattern used follows.

Scenario 1:
Suppose there is a need to iterate over two arrays VALUE_ARRAY_ID, and VALUE_ARRAY_IDEXT, extracting the (String) values from each arrays for the current position each time, and using them in some loop body activities. For simplicity, this loop assumes that VALUE_ARRAY_ID and VALUE_ARRAY_IDEXT are the same length.

Scenario 3:
Scenario 3 is the same as scenario 2 except that Java iterators are now being used - this may not work in MDM as it currently stands as of MDM 8.3.2 hotfix 1 or lower versions of CIM/MDM - it depends on whether Iterator, when specified as a "recordlist" parameter, will actually be treated as a java.lang.Object.
