In the Flow module we have the versions and revisions of the flow, we will understand these features better.
Version management is a control for reusing drawings that were saved during a flow elaboration.
This version history is maintained only while we are in the elaboration stage, making the flow design, after submitting for evaluation it is no longer possible to access these versions.
So, if it is necessary to resume a previous version of the drawing, we can restore that version.
The flow review is used when we have an approved flow and it undergoes changes, to update it it is necessary to generate a new review.
The revision number of the flow is identified in the code.
The issuer or the person in charge can generate a new revision of the flow.
