@Learner-in-Prog - while i was trying this out in our instance, i came across one support document, it says, as below,
"if both csm and telco order management are installed on the same instance. Both sn_csm_order_mgmt and sn_ind_tmt_orm plugins cannot co-exist on the same instance. There are few validations which are hindering order line items to be created if both plugins exist."
may be you are trying form CSM and not installed telecom?
