需求：销售普通发票审核后，自动开具金税发票，不需要点击“金税发票开具”按钮

public class CreateIV : AbstractOperationServicePlugIn

            }

                GoldenTaxServiceHelper.PushGTInvoice(this.Context, "IV_SALESOC", "IV_GTINVOICE", sourceBills, operateResults, true, "0");
                //GTCommonFunction.ShowOperateResult(this.View, operateResults);
                #endregion
    
               //下推失败记录信息到操作日志
                var logs = new List<LogObject>();

                            pkValue = "0",
                            Description = op.Message,

}

注：

1.具体可反编译销售发票单据的表单插件Kingdee.K3.FIN.IV.Business.PlugIn.GoldenTax.GTOperateEdit中的BarItemClick方法自行查看，最终是调用GoldenTaxServiceHelper.PushGTInvoice方法真正进行开票。

2.以上代码不涉及超额拆分开票的情况
