Defining AOI is mandatory in ArcGIS workflow manager? . My requirement is to develop workflow management system for my organization without defining AOI, if it is possible kindly share me the reference links.
Define AOI is not necessary in Workflow Manager system. Your workflow jobs can exist without AOI. If you are looking at the sample workflow provided in the Workflow Manager database and update it based on your organization request, you can remove the Define AOI step from the workflow. You can also design your own workflow without the step.
