Hi, Using a workflow, I'm trying to change the form to Sale Order - Cash, for a specific location. The workflow changes the form, but resets the Location. Does anyone have any idea why?

you could add another action to your workflow after the form change, that sets the location back to the value you want. State 1: Action - Set Field Value: Form -> “Sale Order - Cash”. State 1: Action - Set Field Value: Location -> Desired location.

Thanks @Marc. The location can be different, so I don't want to hard code it. I want to keep the same location in “Sale Order - Cash” after the form has changed.

Create a Workflow field and Set the initial Location to this Workflow field. Then after your form change, Set the Location with the value from your Workflow field.
