Can the CEWB have the goods/e-way bills that are to be delivered prior to reaching the destination specified for CEWB in the "consolidated eway bill" (CEWB).

Yes. The consolidated eway bill can contain the goods or eway bills that will be delivered to multiple addresses as per each EWB in the CEWB. If the CEWB contains 10 EWBs for moving 3 consignments towards destination Y and 7 to destination destination X, the transporter can then deliver 3 consignments at destination Y from the 10 and move the remaining 7 consignments toward destination X using the same CEWB. You can also generate two CEWBs for three consignments to destination Y, and one CEWB for seven consignments to destination X.
