Can order holds and/or credit check holds be placed on payment terms? P0014/P4210

I am currently reviewing the current set up for credit and order holds configured within our EnterpriseOne 9.1 tools release 9.1.5.3 platform.  New sales order are integrated from CRM/Big Machines through TIBCO and we have somewhat straight forward rules/criteria:  What I can't seem to put my finger on is what controls whether or not a payment term defined as cash is controlled?

1. ) Any ‘Ship To’ with payment terms of ‘DNS’ will be stopped in CRM and not come into E1. (Controlled via TIBCO)
   
2. ) If  the ‘Request Date’ of an order is more than 45 days in the future it WILL NOT be put on Credit Hold. (Controlled via Branch plant constants)
