Reorder Point Planning

Which Tasks Are Performed During Reorder Point Planning in SAP S/4HANA?

Let’s face it, MRP in SAP can get confusing, fast. And when you throw in terms like "reorder point planning," things often go from complex to downright overwhelming. So, let’s slow it down and break it apart. Here's everything you need to know about the tasks SAP performs during reorder point planning, explained like you’re talking to a colleague who’s been there.

Top Question:

Which of the following tasks does the system perform during reorder point planning?
Note: There are 2 correct answers.
A. Carry out a lot-size calculation for every material with net requirements.
B. Perform backward scheduling to determine the availability dates of purchase requisitions.
C. Carry out a net requirement calculation for every material included in the planning run.
D. Flag materials that have been subject to an activity relevant to MRP.

Correct Answers:

✔ A. Carry out a lot-size calculation for every material with net requirements.
✔ B. Perform backward scheduling to determine the availability dates of purchase requisitions.

What Is Reorder Point Planning in SAP, Really?

Think of reorder point planning as SAP’s way of keeping your shelves from going empty, without obsessively recalculating every supply and demand scenario like full-blown MRP runs do.

Here’s the gist: When the stock for a material drops below a set reorder point, the system says, “Hey, it’s time to restock.” That’s when it springs into action, kicking off procurement proposals like purchase requisitions or planned orders.

Now, let’s dig into what each of those answer options really means and why only two of them make the cut.

A. Carry out a lot-size calculation for every material with net requirements. ✅

You know how you don’t just order “some” stock, you want the right amount? That’s what this is about. SAP doesn’t just trigger a purchase when stock is low; it also calculates how much to buy using the lot-sizing rules defined in the material master.

Whether it’s a fixed lot size, lot-for-lot, or top-up to max stock, this step ensures you’re replenishing smartly, not blindly. That’s why this task is a core part of reorder point planning.

B. Perform backward scheduling to determine the availability dates of purchase requisitions. ✅

This one’s all about timing. Once SAP decides a material needs to be reordered, it doesn’t just throw out a purchase requisition and call it a day. It works backward from the date the material needs to be available and figures out when the procurement process should actually begin.

This includes planned delivery time, purchasing processing time, and maybe even a bit of goods receipt time. Backward scheduling ensures that materials show up right when you need them, not too early, not too late.

C. Carry out a net requirement calculation for every material included in the planning run. ❌

This is where a lot of people get tripped up. A net requirement calculation is something you’ll find in deterministic MRP, like MRP type PD, not in reorder point planning.

Why? Because reorder point planning doesn’t care about sales orders, reservations, or production orders. It only cares if your stock is below the reorder point. If it is, it reacts. If not, it stays quiet. No full-blown netting involved.

So, this one doesn’t belong here.

D. Flag materials that have been subject to an activity relevant to MRP. ❌

Flagging materials sounds helpful, right? But it’s more relevant in other MRP procedures, specifically when you’re using net change planning (NETCH or NETPL), where materials get re-evaluated if something has changed (like a new sales order or stock movement).

Reorder point planning doesn’t go around tagging materials that had activity. It simply checks stock levels, compares them to the reorder point, and makes a decision. No flags, no fuss.

Quick Recap:

If you’re sitting in front of an SAP exam question or just trying to explain reorder point planning to your team, here’s the bottom line:
  • ✅ Lot-size calculation (A) is definitely done, it tells SAP how much to order.
  • ✅ Backward scheduling (B) ensures SAP knows when to order to hit the availability date.
  • ❌ Net requirement calculation (C) is not part of reorder point planning, that's more of an MRP PD thing.
  • ❌ Flagging materials (D) is a feature of net change logic, not reorder point planning.

Final Thought:

Reorder point planning is like your low-stock alert system, but smart. It triggers procurement only when needed, calculates how much to order, and works backward to make sure delivery is on time. It’s perfect for materials with stable, predictable consumption and minimal volatility.

Understanding the subtle differences between reorder point planning and other MRP types isn’t just exam-critical, it’s the key to building lean, responsive inventory strategies inside SAP.

So the next time you hear “reorder point planning,” remember: it’s all about stock thresholds, smart lot sizes, and timely replenishment, nothing more, nothing less.
