Hana Studioのインベントリエージング計算ビュー

Question

在庫確認が必要な製品のエージングを維持する必要があるhanaスタジオで計算ビューを作成したいとします。

それは以下 がある..私はその後、5500 1000はまず、それがゼロになるまで、量はそれほどで2000を減算しますバランス差し引きます製品P001の場合には意味...最初の最初の基礎を来るを上差し引きます

Department |Product | Date    | Quantity |Indicator 
------------+---------+--------------------+-----------+--------- 
D001  |P001  | 01-Jul-2017  | 1000  |ADD 
D001  |P001  | 10-Jul-2017  | 2000  |ADD 
D001  |P001  | 15-Jul-2017  | 3000  |ADD 
D001  |P001  | 16-Jul-2017  | 2000  |ADD 
D001  |P001  | 18-Jul-2017  | 5500  |SUBTRACT 
D001  |P002  | 12-Jul-2017  | 3000  |ADD 
D001  |P002  | 14-Jul-2017  | 2000  |ADD 
D001  |P002  | 15-Jul-2017  | 4000  |SUBTRACT 

最後の出力は次のようになります。今日の日付が2017年7月31日の場合

Department |Product | Date    | Quantity |AgeinginDays 
------------+---------+--------------------+-----------+--------- 
D001  |P001  | 15-Jul-2017  | 500  |16 
D001  |P001  | 16-Jul-2017  | 2000  |15 
D001  |P002  | 14-Jul-2017  | 1000  |17 

Answer 1

私はインベントリテーブルを作成し、サンプルデータを入力しました。 これは、そのためのSQLコードです。あなたが将来的に助けを求めているとき、そのようなメタデータを共有してみてください:)

create column table InventoryItems 
(
Department varchar(10), 
Product varchar(10), 
Date date, 
Quantity int, 
Indicator varchar(10) 
); 
insert into InventoryItems select 'D001','P001','20170701',1000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P001','20170710',2000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P001','20170715',3000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P001','20170716',2000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P001','20170718',5500,'SUBTRACT' from dummy; 
insert into InventoryItems select 'D001','P002','20170712',3000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P002','20170714',2000,'ADD' from dummy; 
insert into InventoryItems select 'D001','P002','20170715',4000,'SUBTRACT' from dummy; 

サンプル・テーブルおよびデータの準備ができたら、私は高齢化のためのSQLScriptコードに従って調製しました。それは多分難しい理解し、コードを追跡するので、私はあなたの問題を共有し、stock aging SQL calculation on SAP HANA database

で詳細なソリューションを提供し、ここであなたが

with Ins as (
    select 
     row_number() over (partition by Product order by date) as AddId, 
     *, 
     sum(Quantity) over (partition by Product order by Date rows unbounded preceding) as sumIn, 
     sum(Quantity) over (partition by Product order by Date desc rows unbounded preceding) as sumX 
    from InventoryItems 
    where 
     Indicator = 'ADD' 
), Outs as (
    select 
     row_number() over (partition by Product order by date) as AddId, 
     *, 
     sum(Quantity) over (partition by Product order by Date rows unbounded preceding) as sumOut 
    from InventoryItems 
    where 
     Indicator = 'SUBTRACT' 
), Inv as (
    select 
     ins.Product, max(sumIn) - max(ifnull(sumOut,0)) as inv 
    from Ins 
    left join Outs 
     on ins.Product = outs.Product 
    group by ins.Product 
), calc as (
    select 
     Ins.*, 
     Inv.inv, 
     inv-sumx as diff 
    from Ins 
    left join Inv 
     on ins.Product = inv.Product 
) 
select 
    Department, Product, Date, 
    case when diff > 0 then quantity else quantity-abs(diff) end as Quantity, 
    DAYS_BETWEEN(Date,current_date) as AgeingInDays 
from (
    select *, 1 as rn from calc where diff >= 0 
    union all 
    (
     select * from (
      select 
       *, row_number() over (partition by Product order by diff desc) as rn 
      from calc 
      where diff < 0 
     ) t where rn = 1 
    ) 
) 
order by Product, AddId 

をあなたの要件を満たす支援するためにSQLコードであり、これは出力され上記のSQLブロックの実行、私はそれが役に立てば幸い
