1.2     Program Description
Entegris’ supply chain staff are keenly aware of the need to keep inventory levels as low as possible to manage costs and operate in a lean manner.  With this in mind, they currently use various SAP reports to track inventory.  None of these reports provide good visibility to inventory being built or scheduled to be built.
With this in mind, Entegris supply chain staff would like to create a report showing projected inventory builds vs. historical consumption, to be used as an analysis tool to identify possible exception situations.     
1.3     High Level Processing Logic
1.       Get materials from MARC with the selection criteria where MATNR IN S_MATNR AND DISPO IN S_DISPO AND DISGR IN S_DISGR AND PRCTR IN S_PRCTR.
2.     Get consumption details for the last 30 days from MSEG for the selected materials and MKPF-BUDAT is between current date – 30 and current date and the movement type is 261, 262, 601 or 602.
SELECT MENGE FROM MSEG FOR ALL ENTRIES IN IT_MARC WHERE MATNR = IT_MARC-MATNR AND BWART  IN (261,262,601,602) AND MKPF-BUDAT BETWEEN SY-DATUM –30 AND SY-DATUM.
3.     Get the quantity of the currently open production orders from the view CAUFV with the AUTYP  = ‘10’ and STLBEZ  = selected materials. (To get the open orders check CAUFV-GETRI(Confirmed date) = space )
      SELECT GAMNG FROM CAUFV FOR ALL ENTRIES IN IT_MARC WHERE AUTYP = ‘10’ AND GETRI = SPACE AND STLBEZ = IT_MARC-MATNR.
4.     Get the quantity of the planned orders from PLAF for the selected materials
SELECT GSMNG FROM PLAF FOR ALL ENTRIES IN IT_MARC WHERE MATNR = IT_MARC-MATNR
5.     Get the monthly forecast from PBED and PBIM for the current month
SELECT PLMNG FROM PBED INNER JOIN PBIM ON PBEDBDZEI = PBIM BDZEI FOR ALL ENTRIES IN IT_MARC WHERE PBIMMATNR = IT_MARC-MATNR AND PBED~PDATU in Current Month.
6.     Get the Open sales order quantity from VBAP for the selected materials. ( to get the open sales order check VBUP-GBSTA(Over all status) <> ‘C’.
       SELECT ZMENG FROM VBAP INNER JOIN VBUP ON VBAPVBELN = VBUPVBELN AND    
       VBAPPOSNR = VBUPPOSNR  FOR ALL ENTRIES IN IT_MARC WHERE VBAP~MATNR =
       IT_MARCMATNR AND VBUPGBSTA <> ‘C’.
7.     LOOP AT IT_MARC.
                  Read the details and display the report.
END LOOP.
8.     On double Click on a row, Display the Production Ordesr, Production Order Quantity , Planned Orders and Planned Order Quantity for the selected row.
If value is entered on the Difference Quantity field on the selection screen, Restrict the output with the entered percentage difference.
