In Episode 5 of the D365 Insights podcast, I interviewed Monica Mwangunga from Mosoftwares who walked us through Master Planning in D365.

Master planning is one of those areas in Dynamics 365 that everyone knows is important… but very few people truly understand end‑to‑end. That’s why Episode 5 of the D365 Insights Podcast is such a special one.

I sat down with someone I’ve worked with for years and genuinely admire - Monica Mwangunga. If you know Monica, you’ll know she’s what we call in recruitment a unicorn: 

✔ Qualified accountant 

✔ Extensive experience across supply chain, manufacturing, production and retail 

✔ Works across both BC and F&O 

✔ Can operate as a Finance Consultant, Functional Consultant, or Solution Architect

What we covered: A practical, real‑world breakdown of MRP in D365

Monica walked us through master planning in a way that cuts through the jargon and gets straight to the point:

➡️ What MRP actually is

A data‑driven engine that looks at sales orders, forecasts, inventory, lead times, capacity and safety stock to determine what needs to be produced, purchased or transferred, and when.

➡️ How D365 decides what materials and capacity are available

It pulls together sales demand, warehouse data, forecasts, purchase orders, production orders, minimax settings, decoupling points and more. In short: your MRP is only as good as your data.

➡️ The planned orders D365 can generate

• Planned production orders 

• Planned purchase orders 

• Planned transfer orders 

• Even planned subcontracting when capacity is short

This is where companies start to see the real value... automation that reflects real‑world constraints.

➡️ The three types of planning in D365

Monica broke down the differences beautifully:

1. Master Planning – short‑term, actual demand

2. Forecast Planning – long‑term, projected demand

3. Intercompany Master Planning – planning across multiple legal entities

If you work in a multi‑entity environment, that last one is a game‑changer.

🏭 From procurement to production: how it all connects

One of the most powerful parts of the episode was Monica explaining how master planning drives procurement and production:

• How purchase orders are triggered

• How vendor collaboration portals keep data accurate

• How production orders flow from sales → planning → procurement → warehouse → production → quality → shipping

She even broke down the full production lifecycle in a way that makes you appreciate just how much happens behind the scenes before a finished good leaves the warehouse.

🧪 BOMs, formulas, costing and real‑world examples

We also covered:

• The difference between BOMs and formulas

• How D365 calculates estimated vs actual production costs

• Real‑world examples from assembly plants and food manufacturers

• The biggest mistakes companies make when implementing MRP

(Spoiler: it’s always data.)

🎧 Why you should listen

If you work in manufacturing, supply chain, finance, or you’re simply curious about how D365 handles complex planning, this episode is packed with practical insights.

Monica has that rare ability to explain complex processes in a way that makes them feel simple, and she brings real project experience to every answer.
