An Iterative Macro will run through every record and then loop the records back through the workflow, repeating the entire process as many times as is specified, or until a condition is met.
Note: Iterative macro properties will only display on the Test tab in the Interface designer. The contents of the Test tab cannot be edited from the Interface Designer.
Start with a working workflow.
From Workflow Properties, select Iterative Macro from the Workflow Type drop down list.
Once the Workflow is saved as an Iterative Macro, each tool in the workflow gets a lightning bolt anchor . Only Interface Tools can connect to these anchors. This anchor indicates that there are Interface elements and actions updating a workflow tool.
Configure the Iterative Macro Properties, found in the Interface Designer (Ctrl+Alt+D) or accessed from the View menu. Click the wrench icon to view the Properties.
Iteration Input: From the drop down, select the Input Data Tool in the workflow that contains the records to use for the iterative process.
Iteration Output: From the drop down, select the Output Data tool in the workflow that contains the records that will loop back through the iterative process.
Maximum Number of Iterations: All processes must end at some point, otherwise they could loop indefinitely. Specify the number of iterations here.
When Maximum Number of Iterations is Hit: choose the preferred behavior. Choices are:
Error: Workflow will error and stop processing.
Warn: A warning message will be issued and any records left over will be outputted.
Output left over records: All records are outputted.
Output Mode: Records are unioned on output, choose the preferred behavior for outputting these records as some may have a different table schema. Choices include:
All iterations will have the same output schema (error if different)
Note: If schema is the same other than field names, it will be a warn the user but continue to output. It is only an error if the field types or sizes change or the # of fields.
