单据头添加基础资料字段，绑定基础资料类型：联系人（是采购管理下面的联系人）；

在过滤这里，添加快捷过滤条件：FCOMPANY in (select FCustId from T_BD_CUSTOMER where Fmasterid in (select Fmasterid from T_BD_CUSTOMER where FCustId =GetValue(FCUSTID))and (FUseOrgId = GetValue(FSALEORGID) or FCustId in (select Fmasterid from T_BD_CUSTOMER where FCustId =GetValue(FCUSTID))))

设置引用属性，可以继续添加基础资料属性字段；
