Dynamics 365 Field Service : Set up inventory and warehouses

In Dynamics 365 Field Service, inventory management plays a vital role in ensuring that your technicians have the right parts at the right time and place. Whether you’re managing a central warehouse, vans as mobile warehouses, or a network of storage locations, configuring Inventory and Warehouses correctly is critical for smooth operations.
This guide will walk you through the technical steps, logical concepts, and best practices for setting up Inventory and Warehouses in D365 Field Service.
Why Inventory & Warehouses Matter in Field Service?
Field Service operations depend on efficient parts management:
- Ensure parts availability for work orders.
- Reduce delays due to stockouts.
- Track stock movements (adjustments, transfers, consumption).
- Support mobile technicians with van stock management.
Dynamics 365 Field Service uses the standard Inventory Management capabilities of Dataverse (Common Data Model) enhanced with Field Service-specific features like:
- Work order products (to consume parts)
- Mobile warehouses (vans)
- Inventory transfers between locations
- Integration with Purchase Orders and RMA
Step-by-Step: Setting Up Inventory & Warehouses
Create Warehouses
A Warehouse in D365 Field Service represents any location where you store inventory.
Steps:
1. Go to Field Service > Inventory > Warehouses.
2. Click New to create a warehouse.
3. Fill in:
- Name: e.g., Central Warehouse or Technician Van - John Smith.
- Warehouse Type: Select Warehouse (for central) or Truck (for vans).
- Address: Useful for centralized locations.
4. Save.
Tip: Treat each technician’s van as a mobile warehouse to track their van stock separately.
Add Products to the System
Products are the parts/items you want to track in inventory.
Steps:
1. Navigate to Field Service > Inventory > Products.
2. Click New.
3. Enter details:
- Name: Hydraulic Pump
- Product Type: Stocked Product.
- Unit Group: Defines the unit of measurement (e.g., Pieces, Boxes).
- Default Unit: e.g., Piece.
4. Save.
Once products are created, they can be stocked in warehouses.
Set Initial Inventory Levels
You need to define starting stock levels per warehouse.
Steps:
1. Navigate to Field Service > Inventory > Product Inventory.
2. Create a new record:
- Product: Select from the list.
- Warehouse: Select where the stock resides.
- Quantity On Hand: Enter initial stock.
3. Save.
This creates a snapshot of stock levels.
Configure Inventory Adjustments (Optional)
For correcting stock levels (due to loss, damage, etc.), use adjustments.
Steps:
1. Go to Field Service > Inventory > Inventory Adjustments.
2. Click New.
3. Fill in:
- Product
- Warehouse
- Quantity Adjusted: Positive for adding stock, negative for reducing.
4. Save.
Setup Inventory Transfers
When moving stock between locations (e.g., central warehouse → technician van):
Steps:
1. Go to Field Service > Inventory > Inventory Transfers.
2. Click New.
3. Enter:
- Source Warehouse
- Destination Warehouse
- Product
- Quantity Transferred
4. Save.
This updates stock levels in both locations.
Associate Products with Work Orders
When creating a Work Order, add products to indicate parts needed or consumed.
Steps:
1. Open a Work Order.
2. Go to Products tab.
3. Add a Work Order Product:
- Product
- Quantity
- Warehouse: From which warehouse/van the product will be drawn.
4. Save.
When the product is marked as Used, stock levels are reduced.
Enable Mobile Technicians for Inventory
Field technicians can view and update inventory via the Field Service Mobile app:
- View van stock.
- Consume parts against work orders.
- Transfer parts to other technicians.
Best Practice: Enable Field Service Mobile offline sync for inventory so technicians always see the latest stock.
Advanced Topics
Integration with Purchasing
- Use Purchase Orders to replenish stock levels.
- When products are received, inventory levels automatically update.
Return Merchandise Authorization (RMA)
- Manage defective parts returns using RMA functionality.
Real-Time Updates with IoT
- Pair with IoT sensors to monitor stock levels in real-time for critical parts.
Best Practices for Inventory Setup
- Use Automated Flows: Set up Power Automate flows for stock alerts when quantity drops below thresholds.
- Define Warehouse Hierarchy: Central → Regional → Vans.
- Regular Audits: Use inventory adjustments to align system stock with physical stock.
- Leverage Mobile Capabilities: Train technicians to update stock usage in real time.
🔒 Security Roles: Ensure only authorized users can perform stock adjustments or transfers.
Reporting & Monitoring
Use Power BI dashboards or Field Service inventory reports to monitor:
- Stock levels across warehouses.
- Frequently used parts.
- Parts movement trends.
- Van stock levels for mobile technicians.
