2.4 库存管理
介绍:库存账龄是在某时间节点,某种或某类存货的库存时间的加权平均值,跟库存周转率关系明显,库存周转率越高,库存账龄越低,可是二者又不是反比关系。不能简单把库存账龄看成库存周转率的一个衍生指标来对待 。
主界面 (如图2.4.1图1)。
目的:一、库存成本的控制。
二、存货跌价准备计提。
功能:【所有导出】将当前页的所有仓库相应的所有产品导出到Excel文档。【选择导出】将当前页选择的的产品导出到Excel文档。【查询】多条件筛选查询数据(如图2.4.1 图2)。【定位】查询某产品定位到某行。假设产品在多个仓库。能够选择下条定位(如图2.4.2 图3)。

从界面上能够看到00我们这里用到的控件有
控件名称 | 说明 |
日期控件(DateTimePicker) | 控件能够在工具箱直接拖动至窗口,拖至窗口后右击属性能够改动控件的样式和各种属性,还能够编辑事件。 |
下拉框(ComboBox) | |
文本(TextBox) | |
button(Button) | |
表格(DataGridView) | |
复选框(CheckBox) |
功能实现:
第一步:数据库
1、表与关系
2.4.4(图4)
表1: 出入库记录明细表(InAndOutOfInventoryRecordList)
InAndOutOfInventoryRecordListID | int - Identity | 主键 | 出入库记录明细ID |
Quantity | decimal (18, 3) | 数量 | |
TheUnitPrice | decimal (18, 3) | 单位价格 | |
InAndOutOfInventoryRecordID | int | 外键 | 存货ID |
TheInventoryID | int | 外键 | 出入库存记录ID |
表2: 出入库记录表(InAndOutOfInventoryRecord)
InAndOutOfInventoryRecordID | int - Identity | 主键 | 出入库存记录ID |
WarehouseID_Dispatch | int | 外键 | 仓库ID_出库 |
ForTheTypeID | int | 外键 | 出入库类型ID |
WarehouseInventory_ID | int | 外键 | 仓库ID_入库 |
OoperateDate | datetime | 操作日期 |
2、模糊查询匹配
第一步:界面层(UIL)代码,写在查询button点击事件
截图效果:
首先选择好模糊匹配定位(比方输入“双”字,假设选择左模糊,则查出“双XX”的产品,假设选择右模糊,则查出“XX双”,假设选择包括能够为左、右模糊加上“XX双XX”,假设是精确查询,则为“双”的产品)
代码:
private voidbtnFixedPosition_Click(object sender, EventArgs e)
{
stringstrRowFilter = ""; //查询条件
stringstrProductName = txtProductName1.Text.Trim(); //定位到筛选后的一行
if(strProductName == "") { return; }
if(radLeft.Checked) //左模糊
{
strRowFilter = string.Format("产品名称 like '%{0}'", strProductName.Trim());
}
else
{
if(radRight.Checked) //右模糊
{
strRowFilter = string.Format("产品名称 like '{0}%'", strProductName.Trim());
}
else
{
if(radContain.Checked) //包括模糊
{
strRowFilter = string.Format("产品名称 like '%{0}%'", strProductName.Trim());
}
else //精确查询
{
strRowFilter = string.Format("产品名称 like '{0}'", strProductName.Trim());
}
}
}
dvtest = newDataView(dtExisting) { RowFilter =strRowFilter };
dttest = dvtest.ToTable();
if(dttest.Rows.Count > 1) //是否筛选后有一行以上
{
btnNext.Enabled = true; //下一个 button 启用
}
else
{
btnNext.Enabled = false; //下一个 button 不启用
}
intTpage = 0;
FixedPosition(intTpage);
}
3、库龄明细查询分析(依据产品ID与相应的存库进行分析)
第一步:数据库的存储过程
if(@Type='btnCountAnalysis_Click_SELECTBeLaidUpQuantity') --查询入库量计算库龄账龄
BEGIN
DECLARE @出入库流水表 TABLE (产品名称 char(30),出入库时间 nchar(10), 出入库数量 decimal,时间 DATETIME) --创建暂时表
INSERT@出入库流水表
SELECT LTRIM(RTRIM(TheProductTable.ProductName)) AS 产品名称,
CONVERT(nchar(10),InAndOutOfInventoryRecord.OoperateDate , 20) AS 出入库时间,
LTRIM(RTRIM(CAST(-InAndOutOfInventoryRecordList.Quantity AS DECIMAL))) AS 出入库数量,
InAndOutOfInventoryRecord.OoperateDate AS 时间
FROM InAndOutOfInventoryRecordListINNER JOIN
InAndOutOfInventoryRecord ON InAndOutOfInventoryRecordList.InAndOutOfInventoryRecordID= InAndOutOfInventoryRecord.InAndOutOfInventoryRecordIDINNER JOIN
TheInventoryTable ON InAndOutOfInventoryRecordList.TheInventoryID = TheInventoryTable.TheInventoryID INNER JOIN
TheProductTable ON TheInventoryTable.ProductID = TheProductTable.ProductID
WHERE InAndOutOfInventoryRecord.WarehouseID_Dispatch!= 0 AND
InAndOutOfInventoryRecordList.TheInventoryID IN
(SELECT TheInventoryTable.TheInventoryID AS 存货ID
FROM TheInventoryTableINNER JOIN
TheProductTable ON TheInventoryTable.ProductID = TheProductTable.ProductID
WHERE TheProductTable.ProductID = 3 AND TheInventoryTable.WarehouseID = 1) --产品ID、仓库ID
UNION ALL
SELECT LTRIM(RTRIM(TheProductTable.ProductName)) AS 产品名称,
CONVERT(nchar(10),InAndOutOfInventoryRecord.OoperateDate , 20) AS 出入库时间,
LTRIM(RTRIM(CAST(InAndOutOfInventoryRecordList.Quantity AS DECIMAL))) AS 出入库数量,
InAndOutOfInventoryRecord.OoperateDate AS 时间
FROM InAndOutOfInventoryRecordListINNER JOIN
InAndOutOfInventoryRecord ON InAndOutOfInventoryRecordList.InAndOutOfInventoryRecordID= InAndOutOfInventoryRecord.InAndOutOfInventoryRecordIDINNER JOIN
TheInventoryTable ON InAndOutOfInventoryRecordList.TheInventoryID = TheInventoryTable.TheInventoryID INNER JOIN
TheProductTable ON TheInventoryTable.ProductID = TheProductTable.ProductID
WHERE InAndOutOfInventoryRecord.WarehouseInventory_ID!= 0 AND
InAndOutOfInventoryRecordList.TheInventoryID IN
(SELECT TheInventoryTable.TheInventoryID AS 存货ID
FROM TheInventoryTableINNER JOIN
TheProductTable ON TheInventoryTable.ProductID = TheProductTable.ProductID
WHERE TheProductTable.ProductID = @ProductID AND TheInventoryTable.WarehouseID = @WarehouseID) --产品ID、仓库ID
ORDER BYInAndOutOfInventoryRecord.OoperateDate; SELECT 产品名称,库龄,CASE WHEN 出入库数量 > 数量 THEN 数量 ELSE 出入库数量 END AS数量
FROM (
SELECT 产品名称,
DATEDIFF(DAY,出入库时间,GETDATE()) AS 库龄, --与今天相比,计算出相差的天数
出入库数量,
(
SELECT ISNULL(SUM(CAST(出入库数量 AS DECIMAL)),0)
FROM @出入库流水表
WHERE 产品名称 =(SELECT ProductName FROM TheProductTable WHERE TheProductTable.ProductID = @ProductID)
AND 出入库时间 <= GETDATE() AND
(出入库时间 <= 出入库流水表.出入库时间 OR(出入库时间 > 出入库流水表.出入库时间 AND 出入库数量 < 0))
)AS数量
FROM @出入库流水表 AS 出入库流水表
WHERE 产品名称 =(SELECT ProductName FROM TheProductTable WHERE TheProductTable.ProductID = @ProductID) and 出入库时间 <= GETDATE() and 出入库数量 > 0
) as计算表
WHERE 数量 > 0
SELECT *FROM @出入库流水表
END
第二步:逻辑层(BLL)代码
///<summary>
///查询入库量计算库龄账龄
///</summary>
///<param name="intProductID">产品ID</param>
///<param name="intWarehouseID">仓库ID</param>
///<returns></returns>
[OperationContract]
public DataSetbtnCountAnalysis_Click_SELECTBeLaidUpQuantity(intintProductID, int intWarehouseID)
{
SqlParameter[] SQlCMDpas = {
newSqlParameter("@Type",SqlDbType.Char),
new SqlParameter("@ProductID", SqlDbType.Int),//产品ID
new SqlParameter("@WarehouseID", SqlDbType.Int),//仓库ID
};
SQlCMDpas[0].Value = "btnCountAnalysis_Click_SELECTBeLaidUpQuantity";
SQlCMDpas[1].Value = intProductID;
SQlCMDpas[2].Value = intWarehouseID;
return myDALMethod.QueryDataSet("InventoryManage_frm_StockLookIntoTheDistance",SQlCMDpas);
}
第三步:界面层(UIL)代码,在具体库龄窗口的Load事件中绑定的数据
截图效果(在主界面点击相应的产品相应的仓库的具体库龄):
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvenNtMTM2NzY3MzQ5NzAw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
截图效果(具体库龄的主界面): watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvenNtMTM2NzY3MzQ5NzAw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
左边为产品相应的库龄与及相应库龄的数量,右边为相应产品的出入库情况(时间、数量)
截图效果(点击同样库龄合并数量): watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvenNtMTM2NzY3MzQ5NzAw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">
将同样库龄的数量加起来(为什么出现同样库龄?由于在某天对该产品的进出次数多。)
代码:
(一)Load事件:
DataSet dsAgeAnalysis =myfrm_StockLookIntoTheDistance.btnCountAnalysis_Click_SELECTBeLaidUpQuantity(intProductID,intWarehouseID);
dgvInventoryAgeAnalysis.DataSource = dsAgeAnalysis.Tables[0]; //查询库龄
dgvDiscrepancyAgeAnalysis.DataSource = dsAgeAnalysis.Tables[1]; //具体出入明细
ChangeColour(); //出库标识 入库 标识 颜色
(二) 合计数量
#region 合计
///<summary>
///合计
///</summary>
///<param name="sender"></param>
///<param name="e"></param>
private voidbtnTotal_Click(object sender, EventArgs e)
{
listAgeAnalysis.Clear(); //又一次点击时,清空库龄集合
DataTable dtSumAgeAnalysis = new DataTable(); //保存合计的库龄
dtSumAgeAnalysis = ((DataTable)(dgvInventoryAgeAnalysis.DataSource)).Clone();
for (int intRows = 0;intRows < dgvInventoryAgeAnalysis.Rows.Count; intRows++)
{
if (!listAgeAnalysis.Exists(i => i ==Convert.ToInt32(dgvInventoryAgeAnalysis.Rows[intRows].Cells["库龄"].Value)))
{
listAgeAnalysis.Add(Convert.ToInt32(dgvInventoryAgeAnalysis.Rows[intRows].Cells["库龄"].Value));
dtSumAgeAnalysis.Rows.Add();
dtSumAgeAnalysis.Rows[dtSumAgeAnalysis.Rows.Count - 1]["产品名称"] =dgvInventoryAgeAnalysis.Rows[intRows].Cells["产品名称"].Value;
dtSumAgeAnalysis.Rows[dtSumAgeAnalysis.Rows.Count - 1]["库龄"] =dgvInventoryAgeAnalysis.Rows[intRows].Cells["库龄"].Value;
dtSumAgeAnalysis.Rows[dtSumAgeAnalysis.Rows.Count - 1]["数量"] = 0;
}
if (listAgeAnalysis.Exists(i => i == Convert.ToInt32(dgvInventoryAgeAnalysis.Rows[intRows].Cells["库龄"].Value)))
{
dtSumAgeAnalysis.Rows[dtSumAgeAnalysis.Rows.Count - 1]["数量"] = Convert.ToInt32(dtSumAgeAnalysis.Rows[dtSumAgeAnalysis.Rows.Count- 1]["数量"])
+ Convert.ToInt32(dgvInventoryAgeAnalysis.Rows[intRows].Cells["数量"].Value);
}
}
dgvInventoryAgeAnalysis.DataSource = dtSumAgeAnalysis;
}
#endregion
(三)出库标识 入库 标识 颜色
///<summary>
///出库标识 入库 标识 颜色
///</summary>
void ChangeColour()
{
for (int intRows = 0;intRows < dgvDiscrepancyAgeAnalysis.Rows.Count; intRows++)
{
if (Convert.ToInt32(dgvDiscrepancyAgeAnalysis.Rows[intRows].Cells["出入库数量"].Value) > 0)
{
dgvDiscrepancyAgeAnalysis.Rows[intRows].DefaultCellStyle.BackColor= Color.Gold; //为入库
}
else
{
dgvDiscrepancyAgeAnalysis.Rows[intRows].DefaultCellStyle.BackColor = Color.OldLace; //为出库
}
}
}
