Research&Practice In Circulation Enterprises SAP Implementation

Following the progress of domestic circulation enterprises informationization,ERP has became the most effective approach to improve enterprisesinformationization level and resolve management bottle-neck. More and moreenterprises adopted SAP because it with perfect functions, mature implementationmethodology, and plenty of practice experiences. It will be a tough working for anyone enterprise that implementing SAP. Specially, when circulation enterprisesimplement SAP it always go with the issue of integrating with front-end POS.Although SAP provided the standard REATAIL/POS solution, but the standardsolution can not cover all kinds of business requirements because the differences existdifferent industrise even different enterprises. At the same time, because POSproviders may lack deep understanding about SAP, they nearly have no capacity tobring out comprehensive integration solutions with SAP. So, for those circulationenterprises that implement SAP，it always the best serious restriction that how tointegrate SAP with POS on business process level.The paper put forward the improving on method of integration SAP with POS.Firstly, the paper analysed general integration technology. And then the paper make adiscussion about all kinds of integrate technology, including BAPI, RFC, ALE, etc, and selection methodology in integration. Base on above, the paper extended themethodology of SAP interface analysis, and brought forward the solution forintegration SAP with POS on business flow layer. Firstly, we should make a decisionthat which transaction should be handled within which one business system, and makethe definition about the working interface between different systems when entirebusiness flow be dealed with. According to these, we can draw about the interfacescope. Secondly, we can choose the relevant interface technology. At this phase, onthe base of SAP interface techniques selection method, the paper added some itemssuch as system responding time, throughput, system loading, etc. Besides, the papermade a comparison with grid and offered references for interface decision. At last, thepaper made detail analysis and design for those interfaces that be used in integrationSAP with POS, and gave detail describe for those important interface.The paper also made the discussion about two problems solutions for circulationenterprise improving order achievement rate. One is the conformation mechnisam forstock available amount in POS orders. Another is approving POS order integratedwith SAP. How to make promises to goods requirement of POS orders by stockamount in SAP is one of core issues that circulation enterprises focus on. Withanalysis of SAP ATP (Availavle-to-Promise), the paper put out realization POS orderpromise strategy base on SAP ATP. By the interface integration, SAP can putfeedback result to POS system.For those orders not be full promised in POS, SAP cannot refresh them automatically when stock amount be replenished. In order to resolvethis problem, the paper put up the POS order promised number refreshing methodbase on SAP standard ATP function and interface integration. And then, the paperdiscussed the optimization about order examine-and-approve processe between POSand SAP. By interface integration, SAP could decide approving authorityautomatically according to business logics embedded in SAP, and the order can be sent to appropriate person with approving authority automatically. In subsequent POStransaction, transaction handling would be guided by order approving status that beaccessed in SAP via interface. Integration of order examine-and-approve betweenPOS and SAP shorten the complete cycle-time of single business transactioneffectively.The SAP and POS integration method be discussed in paper realized enterprisecore business uniformity, which from POS-end sales to stock management to internalcontrolling. The method increased precision that POS-end performs promise tocustomer. Integration of examine-and-approve improved single transactionsprocessing efficiency. Order achievement rate and business processing circle indexincreased obviously. Exactly matching between order requirement and stockdecreased stock cost and raised stock turnover rate. Otherwise, data analysis aboutincompleted order also offered real data supporting for enterprise subsequentpurchasing decision and product expandedness decision.
