Quote to Order linkages

Hello,

I have to prepare a report where I need to show which all Quotation has been converted to Order.

I have been asked to use FM  CRM_ORDER_READ and tables CRMD_ORDERADM_H/I . I understand that both Quote and Order data are stored in the same table and they differ in the process_type.

I wanted to know what is the relationship that exists between the Quote and Order data. i.e. how can I fetch the orders for a particular quote.

Any input would be really appreciated as I am new to CRM.

Thanks,

Ankit
