Hi,Kamesh!

Thank you for your reply.I modified my source as that you tell me.As below:

LW_HEADER-GUID = 'E1198B5ED59B06F1A107984BE1014782'.
APPEND LW_HEADER TO LT_HEADER.
LW_PARTNER-REF_GUID = 'E1198B5ED59B06F1A107984BE1014782'.
LW_PARTNER-PARTNER_NO = '0080006382'.
LW_PARTNER-KIND_OF_ENTRY = 'C'.
APPEND LW_PARTNER TO LT_PARTNER.
LW_INPUT_FIELDS-REF_GUID = 'E1198B5ED59B06F1A107984BE1014782'.
LW_INPUT_FIELDS-REF_KIND = 'A'.
LW_INPUT_FIELDS-OBJECTNAME = 'PARTNER'.
LW_INPUT_FIELDS-FIELDNAME = 'KIND_OF_ENTRY'.
APPEND LW_INPUT_FIELDS TO LT_INPUT_FIELDS.

And add FM'BAPI_OPPORTUNITY_CHANGEMULTI'.

But it doesn`t work as before.
