The sales order line item will be at ATO level. SMT factory is in the MTS mode, producing according to forecast. There is a SMT inventory warehouse for SMT boards. ATO factory perform the final assembly and testing when Huawei receives the order. In simple words, ‘Planning at the ATO level’ is ATO. The ‘Planning at the SMT level’ is MTS (Made To Stock). ATO’s are unique to customers whereas SMT’s are not. Thus, multiple unique ATO’s share mon SMT. MDS In MDS phase, planners gather all the forecasts first. Then check and adjust the forecasts. After confirming the forecasts, the planners gather all the demands together, that mainly ing from the following four ways a. Demands from marketing plan department b. Demands from the business department (real sales orders) c. Internal demands between different departments d. Independent requirements from different departments After this phase, planners know all the demands that needed to be planned. MPS To generate MPS, planners first generate a MPS plan and get the relation reports. Then they adjust the MPS result before sending to the planning manager for approval. After the planning manager confirmed the MPS result, the planners need to maintain the new MPS plan. Then the MRP scheduling plan is generated. When adjusting the MPS plan, the planners consider the five factors below: a. Version change b. The capacity constraint of the key resources c. The requirements change from the marketing, and changes in internal requirements 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL d. The planning percentage e. Other things such as basic data not accurate, the planning attribute not correct and special orders etc. pl a n ne r ss c he d u l e MP S001?MDS d ataP l anni ng m a nagerga t he r r e po r t002r e po r t e r sc he c k M PS0 0 4006sch ed ul e MRPa d j us t M PS0 0 3ou tp ut005m ai n tian M P S?MRP sch edu ling resu lt PURCHASING ? Purchasing forecast There are two types of purchasing forecast, one is weekly forecast, and the other is monthly forecast. Weekly forecast covers three months purchasing forecasts. The materials are mainly locally supplied. And the purchase lead time are relatively short. Some examples are packaging materials, PCB etc. Monthly forecast covers nine months purchasing forecasts. Special materials are only purchased when the real sales orders are received. They are manually managed and released. ? The MAX/MIN method allows MAX and MIN inventory for the materials. When the material’s inventory is lower than the MIN value, they will be purchased use the following formula: Purchase quantity = MAX – Inventory – PO (time based) + Required quantity of sales order (time based) 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL Ramp。D material planners manually plan and enter the PR of the material for Ramp。D’s exclusive use. MANUFACTURING PLAN The planners generate the production reports using the manufacturing data of the first three weeks. Planner only releases the manufacturing orders that begin in the next two days in the manufacturing execution system. Normally planners only release work orders when the materials of work order are all ready in the inventory. But in some urgent cases, they also release the work order even when not all the materials are all ready. The shortage material may be arriving within the following two days. Work orders for special AI are released when the actual sales orders are received. 169。 2020 i2 Technologies, PROPRIETARY and CONFIDENTIAL BUSINESS SCENARIOS Introduction: Based on the interview questions and discussions with Business Units process owners and factory schedulers, various business scenarios that represent FP’s business requirements have been piled.
