No Transaction Type list in CRMD_ORDER

Hai Experts,

When we give CRMD_ORDER - Business transaction - create, the system is not displying any transaction list to create(empty list), there is no problem with authorizations, but if i maintain channel for any particular transaction type, then that is being displayed, kindly advise how to get the entire transaction list in CRMD_ORDER,

Thanks and Regards,
