Use a general workflow for an internal information request.
Steps
Open Workflows, select View workflows under General, then New workflow and Create.
Name the request, choose the financial year and select the entities that must respond, for example a whole region. Select Save and next.
A general workflow starts without tasks. Select Add task to create the request itself. Name it and describe what you need.
Use Request data to choose the figures, documents or confirmations each entity must provide, and assign it to the local responsible.
Turn on Approvals, so a reviewer checks each answer before it counts as done.
Add the final task: preparing the head office deliverable, assigned to the group tax team.
Keep Tasks must be completed in order turned on, so the final task only opens once the data is in and approved.
When you start the workflow, every entity gets its request, and the answers come in under Collected data.
