Please help me in this regard.   I have tried with FM 'BAPI_OPPORTUNITY_CHANGEMULTI'   But I am unable to understand how to pass the partner values to it.
L_Guid = it_CRMD_ORDERADM_H-guid.      ."'4582EEBA723000A500000000837FBA1A'.
  INSERT L_Guid INTO TABLE Lt_Header.
*move  '43A15126B7A2006502000000837FBA1A' to Lt_Header.

Hi,
Two problems that I found in the mentioned code are:
<b>1. ls_input_field_names-fieldname = 'PARTNER_NO'.
INSERT ls_input_field_names INTO TABLE ls_input_field-field_names.</b>
In between these two lines you should also add the following line:
<b>ls_input_field_names-changeable = space.</b>
<b>2. w_uname = 'salesrep1.</b>
I am not sure if you can pass the user name directly instead of the BP number. There are some standard function modules for getting the BP number from user name. You can use that and then assign the BP number.
Hope this helps!
