Even though envelope checks the Exclude from BOM check box and greys it out by default it still is included in the EPDM BOM. If Exclude from BOM is checked by itself it does not show up in the EPDM BOM. Is there a way to set a variable when envelope is used and stop it from transitioning throught the workflow? We are trying to automatically upload a bill through a workflow transition and if the enveloped parts get included it could be very costly.
