How to Understand Fixed and Variable Production Costs in SNP and PP/DS

Executive Summary There are fixed and variable production setup costs for SNP and PP/DS. We cover how they are used and, what fixed and variable production costs are frequently set up in practice. We cover how well setup costs are maintained on projects. Introduction to Fixed Costs and Variable Production Costs in SAP SNP and SAP PP/DS…

How to Delete PP/DS Orders

Executive Summary There is a specific way to delete orders in PP/DS. There is an essential reason for deleting PP/DS orders. Some production orders can end up being “sticky” or difficult to delete. Introduction APO has a transaction called /N/SAPAPO/RLCDEL, which will delete SNP orders. Very surprisingly, this is listed on some websites as /N/SAPAPO/RLCDELETE, which…

How to Understand The PP/DS and SNP Setup Matrix and Changeovers

Executive Summary PP/DS and SNP in APO both use a setup matrix which provides the system with information regarding changeovers on the production floor. Within the setup, matrix are setup groups that will control the sequence of the production plan and schedule. Introduction The Setup Matrix is a table in PP/DS that holds the timings…

How to Understand The Problems with the SAP PP/DS Optimizer

Executive Summary The PP/DS optimizer has hypothetical benefits that never are actualized in an implementation. Both SAP and SAP consulting partners have been lying to prospects about the PP/DS optimizer’s implementation history. The PP/DS optimizer uses finite and infinite resources. Planning orders can be converted into production orders. Benefits of the PP/DS Optimizer The benefit…

How to Understand The Production Scheduling and the DS Planning Board

Executive Summary There is a distinction between production planning and production scheduling. We cover the detailed planning scheduling board, which is more of a placeholder than a solution. The Differences Between Production Planning and Production Scheduling The difference between scheduling and production planning can be confusing to many people. I will discuss two modules in…

Finite and Infinite Scheduling in PP/DS

Executive Summary PP/DS finite scheduling and its issues Resource maintenance The problem with how many large consulting companies like IBM approach discussing constraints with the client. Being in constraint denial Constrained or Unconstrained Detailed Scheduling It’s essential to consider and evaluate the use of the sentence PP/DS performs finite based scheduling. The reason it is…

How to Understand SAP APO Resources and Resource Types

Executive Summary SAP APO has various resource types, but only a limited number are commonly used, and the resource types differ from one another in important ways and differ per APO module. Introduction Resources are the mechanism for constraining the plan in SAP APO and determining if a plan is feasible. In this article, we…

How to Understand PPDS Production Planning and Scheduling Heuristics

Executive Summary SNP and PPDS both use heuristics. We cover what are the different heuristics in PPDS and the two heuristics used by SNP. How frequently are the PPDS heuristics implemented versus the optimizer on actual projects? Introduction: The SNP Heuristic Versus the PPDS Heuristics As opposed to PPDS, there is just two SNP heuristic….

How to Understand APO Resource Capacity Variants

Executive Summary Resources are used by SAP SNP and allow for capacity variants, which are optional resources. APO resources can be either capacity leveling and capacity constraining. Changes are made to SNP resources, which are covered in this article. Introduction to Resources in APO Resources are what represent physical capabilities in the supply network. You…

How to Understand Resources in SAP APO

Executive Summary Resources are how capacity is managed in SAP APO. Different resources are used per APO module, while mixed resources can be used for either SNP or PP/DS. We cover front loading as a requirement that is backward versus forward scheduling. Introduction to Resources There are multiple resources in SAP APO. These are designed…
