Use the Process Model window to remove the relationship between a given source and a step. You might do so if you want to use a different source for the step.
To remove a source from a step:
Right-click the link between the step and the source.
Click Remove to remove the link between the source and the step.
The step no longer uses that source. The source remains in the Process Model window.
Click Process --> Save to save the changes that you have made to the process.
