Executive Summary PP/DS uses two methods for performing planning and scheduling. In this article, we cover capacity level versus capacity constraining. We cover fixed versus dynamic pegging, lot size settings, planning sophistication versus ERP, heuristic planning, ATP’s accuracy, how resources are managed, PP/DS with process industry planning, and the PP/DS release history. Introduction Production Planning…
Executive Summary Optimization in SAP APO has failed in both SNP and PP/DS. There are repeated problems with cost settings, and this failure is widely censored by SAP consulting companies that prefer to bill customers for what is a dead solution. An Appraisal of the True State of Optimization in SAP APO If one looks…
Executive Summary Supply and production resources can be aggregated in SAP APO. SNP has both resource aggregation and disaggregation. There are important prerequisites to hierarchical planning. Introduction Different domains of the supply chain have different types of resources that must be modeled. For instance, trucks are a resource for supply planning, while a workstation is…
Executive Summary Identifying the disconnection points. Labor pools The Time Dimension of SNP Versus PP/DS. Understanding the Standard Sequential Approach to Supply and Production Planning. Disconnection Points Between Supply and Production Planning in APO There are several disconnection areas between supply planning and production planning applications like SNP and PP/DS as a model for the…
Executive Summary APO has shared resources between SNP and PP/DS, which is called the mixed resource. There are critical differences in assumptions between SNP and PP/DS. In this article, we compare these two applications to how another application manages shared resources. Introduction In the vast majority of cases with APO, SNP, and PP/DS share the…
Executive Summary The requirements for vendor capacity modeling have been driven in part by contract manufacturing, where the outsourced plant is not a typical supplier but rather a slave plant. Often the question arises as to whether there is value to using a vendor planning book. There are several approaches to constrain based planning at…
Executive Summary Time continuous and bucket planning can be performed in CTM and PP/DS. We cover the settings necessary for both the CTM Profile and the resources when continuous planning is used. Orders can be converted from both SNP and PP/DS planned orders. Introduction to Time Continuous Planning CTM can plan with bucket or time…
Executive Summary There is a background on synching SNP and PPDS. SNP and PPDS differ in their horizons, and which horizons do what and where and how the SNP Production Horizon and PP/DS Horizon do not overlap. How SNP and PPDS differ by location. Introduction A common question on APO projects is how SNP and…
Executive Summary Labor constraints can be managed with a labor pool in SNP and PP/DS, and ERP. There is a relationship between the labor pool and machine resources. Is APO really the right place to constrain the labor resource? Introduction to the Bottleneck Resource The bottleneck resource is critical to managing production constraints. You will…
Executive Summary There are differences between discrete and repetitive manufacturing both in their business process and in SAP. We cover what is available in SAP ERP and SAP APO in this area and choose the right modeling for a complete set of factories in a supply network. Introduction Repetitive manufacturing is often considered to be…
