BAPI_BUPA_ADDRESS_CHANGE is not updating Service address on BP

I am currently using BAPI_BUPA_ADDRESS_CHANGE to make changes to addresses on the business partners. It is working perfectly when I update address information on the mailing address on the business partner . When I try to update the service address information on the Business Partner Service Address it is not working. What could be the problem?

CALL FUNCTION 'BAPI_BUPA_ADDRESS_CHANGE'

EXPORTING

businesspartner = wa_cs009_infile-buspartner

addressdata = addrdatab

addressdata_x = zaddressdata_x

accept_error = zia_ut=>cc_off

TABLES

return = z_return

EXCEPTIONS

OTHERS = 1.
