Order changes not replicate from R/3 to CRM

Hi,

We have Drop shipment scenario, Material availability acknowledgement updated by vendor in Purchase order. Once updated by vendor, material confirmation date & qty will change accordingly and update in ECC sales order but those changes (confirmation date & qty) not updated from ECC to CRM sales order.

What could be the reason and what configuration require?

Its very very urgent plz.............

thanks in advance

Regards

sai
