Hi,
Can you tell the background of your question? Do you want to disable a version to enable a new version of the workflow, or do you want to skip the workflow process in your organization? Note that an active workflow is required to be used with purchase requisitions to be able to manage the status and then create purchase orders once the requisition is approved.
In case you want to disable a version, you can go to the workflow configuration form, click on versions. Then select the version and click on the action to disable the version. As workflow is required, you need to enable another version.
If you want to skip approval for all requisitions or based on a condition, you can use automatic approval when configuring the workflow version. If that is the case I also wonder about the purpose of using purchase requisitions. You can then also directly create purchase orders.
