以付款申请单为例 ： ##### ~~~Java EntityViewInfo evi = new EntityViewInfo(); FilterInfo filter = new FilterInfo(); //也可用id作为条件 filter.getFilterItems().add(new FilterItemInfo("number","填入付款申请单的单号")); evi.setFilter(filter); //付款申请单 PayRequestBillCollection purReqCol= PayRequestBillFactory.getLocalInstance(ctx).getPayRequestBillCollection(evi); PayRequestBillInfo purReqInfo = purReqCol.get(0); ~~~ #####
