# Unable to edit a process flow

## Scenario

You've accessed an existing process flow but can't make any changes on the canvas - there are no options to add shapes.

## Reason

What you can and can't do with a process flow depends on the version you're viewing. If there are no options to add shapes to the canvas, it's likely that you're viewing a [deployed version](/product-documentation/process-flows/building-process-flows/process-flow-versioning.md#deployed) or an [inactive version](/product-documentation/process-flows/building-process-flows/process-flow-versioning.md#inactive) of the process flow. Only the [draft version](/product-documentation/process-flows/building-process-flows/process-flow-versioning.md#draft) of a process flow can be updated. 

## Solution

Try **one** of the following:

* Switch to the [draft version](/product-documentation/process-flows/building-process-flows/process-flow-versioning.md#draft) of the process flow
* Use the [copy to draft ](/product-documentation/process-flows/building-process-flows/process-flow-versioning.md#copying-to-draft)option to create a new draft version of the process flow

## Further information
