CT1 and ARE1, Merchant Export

Hi All,

My client is purchasing materials and exporting. They do not have Excise Registration. They have bond of Rs.2 Cores with Excise department. When they purchase materials, they apply for CT1 and provide it to the Vendor. When the vendor supplies the materials, he gives the CT1 and ARE1. After export they submit custom authenticated CT1 back to the excise department.

Please suggest me how to map this scenario in SAP and how much standard SAP can support.

Regards

Prashant
