问题场景：
销售订单同步 CRM->ERP,提示交货明细数量与订单明细数量不一致，
1、登录金蝶webapi,得知交货明细是订单下的从对象，且保存后是放在订单明细中的字段，且是数组（只支持订单明细一对一交货明细，不支持一对多）。
2、CRM没有配置交货明细从对象，只有通过同步中函数增加映射的字段。报错截图：
(调用ERP接口报错: 调用外部http接口失败,错误信息：FPlanQty,第1行分录，交货明细的数量与订单明细的数量不一致，请检查.[errCode:5001,J-E.592739.-10000-sync142408-SalesOrderObj_627df9760df66d000144a3fe])处理步骤：
1、同步中函数增加要同步的字段，交货明细
2、映射中配置交货明细字段，设置固定值
Map objectData = syncArg.objectData as Map;
Map detailsData = syncArg.details as Map
List detailsList = detailsData["SAL_SaleOrder.SaleOrderEntry"] as List // 从对象的明细List
DateTime now = DateTime.now()
now = now+1.days
String nowString = now as String
nowString = nowString+":01"
log.info("时间=="+nowString)
Map newDetailsData = [:]
List newDetailsList = []
detailsList.each{ item ->
Map detailsListData = item as Map // 每条明细数据
BigDecimal FQty = item["FQty"] as BigDecimal // 数量
BigDecimal NewFQty = FQty.setScale(2, BigDecimal.ROUND_UP)
String NewFQtyString = NewFQty as String
log.info("数量=="+NewFQty)
Map jiaohuo = ["FPlanDate":nowString,"FPlanQty":NewFQty]
log.info("交货明细数据=="+jiaohuo)
detailsListData.put("FOrderEntryPlan",[jiaohuo])
newDetailsList.add(detailsListData)
}
newDetailsData.put("SAL_SaleOrder.SaleOrderEntry",newDetailsList)
log.info("新的明细数据=="+newDetailsData)
Map map = ["details":newDetailsData, "objectData":syncArg.objectData];
syncArg =map;syncArg["isCover"]="true";
return syncArg;
