Disabling and Enabling Flow Steps and Transformers

Service Development Help : Debugging Flow Services : 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.
