How to test HVGOP functionality before migrating to PRODUCTION environment

Hello Community Experts,

We are currently testing HVGOP in testing env and want to ascertain that HVGOP is indeed enabled and all the new Sales orders are being promised using the new HVGOP correctly (Note that all the pre-requisite steps have been performed like enabling HVGOP(Opt-in), running BOR etc.)

Are there any specific fields on Sales Order screens that should checked to confirm that HVGOP is indeed enabled and being used for new Sales orders. Are there any ESS that should be checked to confirm this.
