SAP MRP & Production Planning, explained by playing it

Material Requirements Planning answers one question: what should we build, and do we have the parts? In Playgramma's MRP Planning module you set up the master data, run MRP, release production orders and turn raw materials into finished goods on your own shop floor — the full SAP PP flow, from recipe to receipt.

First, the master data everything hangs off

Before a single unit is planned, three master records define the product. In the game you build them in order:

• Material Master created MM01 — FG-9001 Gear Assembly now exists: a FERT (finished product) in pieces, for plant 1000. Every other record and document hangs off this material.
• Bill of Materials saved CS01 — the recipe for one Gear Assembly: Steel Coil ×2 and Bearing Kit ×1. MRP explodes it into component requirements and the order consumes exactly these quantities.
• Routing saved CA01 — the steps: Op 0010 Cutting → 0020 Assembly → 0030 Testing, each at its work centre. The routing tells the production order which machines do the work and how long it takes.

Then, the MRP run — the planning phase

Master data is built once; the factory runs on it continuously. Here's the planning loop:

• Demand received MD61 — a planned independent requirement arrives on the Order Board from sales & forecasting and waits in the queue. This is what MRP will plan.
• MRP run MD02 — nets demand against stock and explodes the BOM into dependent requirements, flagging any shortage. MRP is the planning phase — nothing is produced yet.
• Planned Order created MD02 — MRP turns covered demand into a planned order: a proposal, not yet firm. Take it to Production Control to convert & release.

Finally, execution on the shop floor

• Production Order converted & released CO40 · REL — the plan is made firm; the order carries the BOM and routing, and release lets the line start.
• Goods Issue posted MIGO · movement 261 — BOM components are issued from Production Supply to the order, and machine & labour cost is charged as production starts.
• Operation confirmed CO11N — each routing operation is confirmed as its work centre finishes, booking machine and labour time.
• Goods Receipt posted MIGO · movement 101 — the finished Gear Assemblies are received into the output location. Components in, product out — the order is complete.

When MRP finds a shortage

MRP doesn't just plan — it exposes gaps. The game makes you close them:

• Material shortage — a BOM component is missing from Production Supply, so planning stalls until it's covered.
• Purchase Order raised ME21N then Goods Receipt MIGO 101 — the raw material is bought, paid and delivered into Production Supply. This is how MRP shortages are covered in a real landscape — PP handing off to P2P.
