* Jerry: in CL_CRM_OPPORTUNITY_impl=>PATCH_OPPT_HEADER_ENTITY only extension field name
* like "fld00008c" is passed in, and it is impossible for us to determine which BO part this
* extension field comes from, eg from OPPORT_H or CUSTOMER_H?
* as a result, it is necessary for extension developer to specify mapping in this method
