Need help to read the item details while creating the Opportunity in SAP CR

Question

Hi,
I need to read the values entered at item level while creating a new opportunity in SAP CRM 5.0.
Is there any function modle to do that ? I need to read the custom fields (developed by EEWB)
and sum  them up and populate at the header level.
As the data is not saved yet, I cannot read from database in the present scenario.
Thanks and regards

Hi,
  U can use CRM_ORDER_READ.
1) Pass the values for the ITEM guid which u want to read.
2) ignore the other header guid and object id because it is for whole contract
3) if u had custmize any table it will be available in the internal table returned by the function module.
4) u have to identify which internal table will contain the field since many internal table are available with similar meaning.
4) CRM_ORDER_ORDER is heavy function module it reads entire contract hence u need to specify which internal table u have to read any only those values will be read. for that u have to fill in <b>it_requested_objects</b>
fill requested ogject with below statement
INSERT gc_object_name-orderadm_h  INTO TABLE lit_import_tab.
gc_object_name is constant structure u have to include
*-Standard Include
  INCLUDE crm_object_names_con.
Mark helpfull answers
