Hi Brendon ;
1) The name of extractor used for this query is 0CRM_OPPT_H, i want to know if it load the field requested buy a customer, but how i can get the field source name from his screen CRM, they show me a CRM view of opportunities with different field and when i press F1 they all have partner_number in field name ...the customer can't give me either the techical name of table or of field source.
How i can find the functional area? is that mean BW dimension ? please give me an example of functional area for any field (0material for example)
3) how can i find if the field may not be part of standard business content ?
thks for your response 
Regards!
