Inbound Webservice Create LOY Member

I created Member IO via LOY Member BC and use EAI Siebel Adapder upsert it.  when LOY Member BC write record, an OOTB function check duplicate record use:" --Duplicate membership Search Spec: [Program Id] = '1-47TP8'  AND [Primary Contact Id] = 'No Match Row Id' AND [Status] <> '已取消' AND [Id] <> '1-5XZCWZI' AND [Member Type] ='单个'"  searchspec, but at that time my contact has not insert into db, the [Primary Contact Id] keep "No Match Row Id" value.  Did anyone came across the same scenario? and how to set a value to primary contact id not use script ?
