Hi Bhasin,
You need to read through table "CRMD_ORDERADM_H" where the OBJECT_TYPE is "BUS2000270".
See the post linked above from Des with the Grantor tables to see the other OBJECT_TYPES.
You will then need to call FM "CRM_ORDER_READ" and get the import parameter ET_PRIDOC
This provides the pricing information.
You will need to loop through this for all the lines.
You are interested in "6GR1", "6GR2", and "6GR3"
These are the Requested, Eligible and Authorized amounts.
Hope this helps.
Regards, Paul
