获取信用余额

二开案例，在单据上获取到客户的信用余额显示在单据字段上，方案如下：
第一步：在BOS单据上增加相应的信用余额字段；

第二步：确定一个取数触发点，可以是一个按钮，新增表单插件，在插件中用代码实现按钮取数逻辑，代码取数的时候，可以调用信用状况查询的服务方法，取数插件代码如下，分别引用Kingdee.K3.Core.dll、Kingdee.K3.SCM.WebApi.ServicesStub.dll俩个组件类：

            APIQCreditInfoArgs args = new APIQCreditInfoArgs();
                args.OrgNumber = porgNumber;
                args.DeptNumber = pdeptNumber;
                args.ObjectType = pobjectType;
                args.ObjectNumberFrom = pobjectNumberFrom;
                args.ObjectNumberTo = pobjectNumberTo;
       DynamicObjectCollection creditinfos = Kingdee.K3.SCM.ServiceHelper.CreditServiceHelper.GetAPICreditInfo(ctx, args);  

foreach (DynamicObject creditdata in creditinfos)

                {

                    string orgNumber = Convert.ToString(creditdata["FORGNUMBER"]);

                    string objectType = Convert.ToString(creditdata["FOBJECTTYPE"]);

                    string deptNumber = Convert.ToString(creditdata["FDEPTNUMBER"]);

                    string objectNumber = Convert.ToString(creditdata["FOBJECTNUMBER"]);

                    string currencyName = Convert.ToString(creditdata["FCURRENCYNAME"]);

                    decimal creditamount = Convert.ToDecimal(creditdata["FCREDITAMOUNT"]); //信用余额

                    decimal tmpcreditamount = Convert.ToDecimal(creditdata["FTEMPCREDITAMOUNT"]);

                    decimal credituseamount = Convert.ToDecimal(creditdata["FUSECREDITAMOUNT"]);

                    decimal creditbal = Convert.ToDecimal(creditdata["FCREDITBALANCE"]);

                    long overdays = Convert.ToInt64(creditdata["FOCCUPYOVERDAYS"]);

                    decimal overcredit = Convert.ToDecimal(creditdata["FOCCUPYOVERCREDIT"]);

                    string custNumber = Convert.ToString(creditdata["FCUSTNUMBER"]);

                    string salerNumber = Convert.ToString(creditdata["FSALERNUMBER"]);

                    string salegroupNumber = Convert.ToString(creditdata["FSALEGROUPNUMBER"]);

                    long creditoverdays = Convert.ToInt64(creditdata["FOVERDAYS"]);

                    decimal creditoveramount = Convert.ToDecimal(creditdata["FOVERAMOUNT"]);

                    decimal creditlimitamount = Convert.ToDecimal(creditdata["FLIMITAMOUNT"]);

                    long tmpcreditoverdays = Convert.ToInt64(creditdata["FTEMPOVERDAYS"]);

                    decimal tmpcreditoveramount = Convert.ToDecimal(creditdata["FTEMPOVERAMOUNT"]);

                    decimal tmpcreditlimitamount = Convert.ToDecimal(creditdata["FTEMPLIMITAMOUNT"]);

           }

其中，Kingdee.K3.SCM.ServiceHelper.CreditServiceHelper.GetAPICreditInfo这个方法为取信用余额数据的服务方法：FCREDITAMOUNT为信用余额的值

第三步：将第二步取到的信用余额显示到页面上即可：
 注意：这里取到的信用余额是一个瞬时值，并不能作为审核的时候信用余额的判断。
