The Essence of SAP Retail Master Data — my recent blog post — was all about massively creating product data, location data, and product data that’s location specific. This video goes to the next level.
After you’ve brilliantly orchestrated master data to create master data — perhaps billion of rows — how do you maintain this over time … with least effort?
For that, you need to understand a concept called Reference Handling.
The essence of SAP Retail Master Data is manifested at the intersection of Products and Locations. We also call them Articles and Sites, or Materials and Plants. Take your pick; the SAP lexicon is forever morphing for your enjoyment 🙂
Whatever you call them, the number of Products times the number of Locations is a big number in SAP Retail. It quantifies the Retail Master Data challenge, and billions is the typical unit of measure.
You’ve got to massively create and maintain product data, location data, and product data that’s location specific. Yes, please, and with least effort.
A central concept permeates SAP Retail Master Data to enable master data creation: using master data to create master data. If you get your head around this idea — even at a high level — then you’ll begin to grasp the elegance and uniqueness of SAP Retail Master Data.
It would be fair to say that I still dislike eCATT. But the best SAP Functional folks are the best, in part, because they’re aware of every tool in their kit. And sometimes eCATT is the right tool for the job. In rare cases, it’s the only tool for the job.
You should know a bit about eCATT, even if you plan to avoid it, as I do.
It’s a self-serving notion with the added benefit of being true!
Sure, it’s the unique business processes of Retail and Fashion Vertical Business that prompt these Industry solutions. But if you get the foundation wrong — if you fail to grasp what’s special about SAP Retail master data — then you can forget about effectively executing business processes.
Creating master data (and customizing, without customizing requests!) is a serious matter. Your data migration process better be executed properly and accurately. For one thing, it’s a tedious mess to clean up (archive) if things goes awry. Of course, as a Master Data Aficionado reading this article, you now have a plan for success.
Let’s begin by recognizing that your Site Master business process design dictates where and when you’ll be executing Site Master data migration.
Profit Center number decisions that add complexity.
Your decision for Profit Center numbers can add ongoing operation costs and complexity, especially in SAP Retail.
We’re talking strictly about Profit Centers in Material Master that are assigned for each Plant (MARC-PRCTR).
The Best Practice in SAP Retail is that only one Profit Center per Plant (Site) is relevant for all Materials (Articles), and that the Profit Center number is the same as the Plant number.
Profit Center number = Plant number. Simple. But why is this Best Practice? What pitfalls await those who deviate? And how is Best Practice implemented? Spoiler alert: it isn’t standard, and that’s standard!
A notable feature of S/4HANA is that, unlike ECC 6.0, a customizing request is not raised when creating or maintaining a Site Master in the Customizing Golden client. Given this, should a Site Master in S/4HANA be considered as master data or treated as customizing?
What’s more – perhaps, what’s worse – your Site Master process design critically depends on the answer to this “debatable” question. You better get this right.
