Video Introduction: What SAP Said About its the PP/DS Optimizer

Text Introduction (Skip if You Watched the Video)

The PPDS Optimizer is part of the SAP APO suite. It is designed to provide a detailed schedule, down to the minute. It is supposed to allow companies to constrain and to develop an optimal production plan and schedule. However, analysis of PPDS implementation and first-hand experience indicates that the PPDS optimizer is rarely used. There are several reasons for this. PPDS is cost optimization, and cost optimization is not an appropriate objective function for production planning. In nearly all cases that we could find, companies removed the PPDS optimizer either before or not long after the PPDS applications went live. You will learn the accuracy of SAP’s PPDS optimizer.

The Truth About the PP/DS Optimizer

In reality, the PP/DS Optimizer has turned out to be one of the most excellent bait and switch functionality offerings in the supply chain space. The PP/DS Optimizer can be taken live, but only if user acceptance testing is skipped to meet the go-live date. In our evaluation of projects, the implementing company invariably gives up on the PP/DS Optimizer and switches back to using another approach in PP/DS called heuristics. Secondly, SAP and many SAP implementation companies certainly know this, and they continue to recommend using the PP/DS Optimizer for its illusory benefits. We covered these issues in the article The Failed PP/DS Optimizer and Replacing the SNP and PP/DS Optimizer.
