Hi Rishika,
CRMD_ORDER transaction is now outdated to create any transaction in CRM.
You should create service contract from UTIL_IC business role in web UI.
CRMD_ORDER transaction can only be used for display/analysis purpose.
BAPI_BUSPROCESSND_CREATEMULTI - I wouldn't recommend to use this rather use CRM_ORDER_MAINTAIN directly or use class CL_CRM_ISU_ORDER_CHANGE.
In above class you have methods like SET_POD , SET_PRODUCT, SET_DATE, SET_PARTNER etc which will take care of filling data in all required tables.
