When a supplier cannot deliver a large order all at once, creating one big purchase order is not always the best way to manage the requirement.
Procurement teams need to know what can be ordered now, what needs to come later, and how each delivery connects back to the original requirement.
That was the challenge faced by Wuhan Weyeah Power Machinery Co., Ltd. (Weyeah Power) while managing a large range of specialized power plant engine spare parts and equipment for customers across global markets.
To address this, Indictrans introduced a flexible purchase planner workflow that allows procurement teams to plan the total requirement, split it into practical batches, and generate purchase orders based on actual supplier capacity.

The Business Challenge
Managing procurement becomes more difficult when suppliers have their own production and delivery limitations.
For Weyeah Power, the challenge was not simply creating Purchase Orders. The procurement team needed a better way to plan large requirements around what suppliers could actually produce and deliver.
- Supplier Capacity and Delivery Delays
Procurement teams traditionally created bulk Purchase Orders based on internal demand.
However, these orders could sometimes exceed the supplier’s immediate production or delivery capacity. This resulted in:
- Vendor backlogs
- Missed deadlines
- Unpredictable delivery schedules
- Fragmented Order Tracking
When a large order was delivered in parts, the team had to manually track:
- Which portion of the order was arriving
- When each portion was being produced
- How each delivery related back to the original requirement
Managing this through spreadsheets made the process time-consuming and prone to errors.
- Inconsistent Receipts and Quality Checks
Shipments could arrive in random and uncoordinated batches.
This made it difficult for warehouse teams to prepare for incoming inspections and created bottlenecks at the loading docks, which also delayed Purchase Receipts.
The Solution: A Flexible Purchase Planner
The procurement team needed flexibility without losing control of the overall requirement.
To address this, Indictrans introduced a dedicated Purchase Planner framework.
The Purchase Planner works as an intermediate step between the overall requirement and the final Purchase Orders.
Instead of immediately creating one rigid Purchase Order, the procurement team can first create a plan, decide how much should be ordered in each batch, and then generate Purchase Orders based on those decisions.
How the Purchase Planner Works
- Create the Purchase Plan
The Purchase Planner Document acts as the starting point for the procurement process.
The user first creates a complete plan covering the total items and quantities required for the business cycle.
This gives the procurement team a clear view of the overall requirement before creating individual Purchase Orders.
- Split the Requirement Based on Supplier Capacity
This is where the Purchase Planner gives the procurement team more control.
The team can manually divide the total quantity into specific batches based on the supplier’s actual capacity or container limits.
Instead of:
One large requirement → One large Purchase Order
The process becomes:
Total Requirement → Planned Batches → Capacity-Aligned Purchase Orders
The procurement team decides how much should go into each batch, while the system uses those batches to generate sequential Purchase Orders.
This allows the team to work around real supplier constraints rather than forcing every order into a fixed structure.
- Generate Purchase Orders from the Planned Batches
Once the batches are defined, the system generates targeted Purchase Orders based on the user’s plan.
Each Purchase Order represents a specific portion of the overall requirement.
This makes it easier to connect:
Business Requirement → Purchase Plan → Purchase Order → Supplier Delivery
- Manage Incoming Deliveries More Easily
Because the Purchase Orders are structured around what the supplier can actually deliver, incoming shipments become more predictable.
Warehouse teams can prepare for the expected batches and generate Purchase Receipts against the relevant Purchase Orders.
This creates a clear connection between the original requirement and the physical stock received into the warehouse.
What Changed for the Procurement Team?
The Purchase Planner created a more practical way to manage large purchase requirements.
Before
Large requirement
↓
Bulk Purchase Order
↓
Supplier capacity mismatch
↓
Delayed / fragmented deliveries
↓
Manual tracking
↓
Receiving bottlenecks
With the Purchase Planner
Total requirement

↓
Manual batch planning

Capacity-aligned Purchase Orders

↓
Purchase receipts against specific batches
This approach gives procurement teams the flexibility to make decisions based on real supplier capacity, while keeping the overall purchase requirement structured.
Bringing Procurement Planning and Supplier Capacity Together
The key difference is that the workflow does not treat every supplier as if they can deliver in the same way.
The procurement team can use its own knowledge of:
- Supplier capacity
- Production limitations
- Container limits
- Expected delivery schedules
and reflect those decisions directly in the Purchase Planner.
The system then turns those decisions into structured Purchase Orders and receipts.
The Result
By introducing a structured but flexible Purchase Planner workflow, Weyeah Power was able to bridge the gap between planned demand and actual supplier capacity.
The solution helped procurement teams:
- Adapt purchase quantities to supplier capacity
- Break large requirements into manageable batches
- Create sequential purchase orders
- Track each portion of an order more clearly
- Prepare for incoming deliveries
- Manage purchase receipts against specific batches
- Reduce delivery-related delays
- Avoid warehouse receiving bottlenecks
The biggest change was giving the procurement team more control over how a purchase is executed, without losing visibility of the overall requirement.
The Takeaway
For businesses managing large and specialized procurement requirements, the challenge is often not creating a purchase order.
It’s making sure that the purchase order reflects what the supplier can actually deliver.
With the Purchase Planner workflow, Weyeah Power can structure large requirements into practical batches, align orders with supplier capacity, and maintain a clear trail from the original requirement to the stock received.
It brings together procurement planning, supplier capacity, order execution, and warehouse receiving in one more manageable process.
