解决方案：您好，此问题是因为采购发票中的到期日为空造成的。请备份帐套并改为另一个帐套号作为测试帐套并引入产品，对测试帐套执行脚本* d.* into tempdb..purbillvouch_cac*pdatebak from po_pomain as a join po_podetails as b on a.poid=b.poid join purbillvouchs as c on b. id=c.iposid join purbillvouch as d on d.pbvid=c.pbvid where d.cac*pdate is null --此脚本是备份有问题数据，然后查询* cpbvcode as 采购发票 from tempdb..purbillvouch_cac*pdatebak，试试这些采购发票是否均有此问题。
