Disabling and Enabling Flow Steps and Transformers
As part of debugging services, you can disable flow steps and transformers. Disabled flow steps and transformers do not execute. Disabling a step or transformer is useful in many debugging situations. For example, you might want to disable one or more steps to isolate a particular segment of a flow, similar to the way you might “comment out” a section of source code in a program you are debugging.
Keep the following points in mind when disabling and enabling flow steps and transformers:
Disabling a step or transformer sets a persistent attribute that is saved in the flow service. Once you disable a step or transformer, it remains disabled until you explicitly re-enable it with
Designer.
Steps and transformers that you disable are not executed at run time.
The
symbol appears next to disabled steps and transformers.
If you disable a parent step (for example, a LOOP or a BRANCH),
Designer disables its children automatically.
If you disable a MAP step,
Designer disables the transformers in the MAP step automatically.
Disabling a step or transformer removes a breakpoint hosted by that step or transformer.
Important: The run-time effect of disabling a step is the same as deleting it. Disabling a key step or forgetting to re-enable a disabled step or transformer can break the logic of a service and/or cause the service to fail. Designer allows you to disable any step or transformer in a flow service, but it is your responsibility to use this feature carefully.
To disable or enable a flow step or transformer
1. Open the flow service that you want to edit.
2. Do one of the following:
In the editor select the step that you want disable or enable.
In the editor select the MAP step containing transformers that you want to disable or enable.
3. Right-click the step or transformer and do one of the following:
Select
Disable Step to disable the step or transformer.
Select
Enable Step to re-enable the step or transformer.
