1. Introduction
In ProdSys, the purchase order screen can be used not only to create purchase orders, but also to create production orders for semi-finished goods.
This provides an efficient way to handle demand for components used in the production of other products.
2. Prerequisites
For this functionality to work, the following conditions must be met:
The product must be defined as:
Logistics = Yes
The product must be part of a Bill of Materials (BOM) for another product
There must be a demand (sales order, production order, or stock shortage)
3. How demand is generated
ProdSys automatically calculates demand based on:
Sales orders
Production orders
Inventory levels
Reserved quantities
Purchased / ordered quantities
This is displayed in the purchase screen through columns such as:
Stock
Net Available
Reserved
Ordered
Purchase qty (Suggested quantity)
If Net Available is negative, it indicates a need to supply the item.
4. Creating a production order
Step by step
Go to Purchase → Create purchase order
Select:
Warehouse
Delivery date
Find relevant items in the list
Check the Purchase qty column for suggested demand
Select the desired lines
Important selection
In the Supplier field:
The supplier must be your own company
Select your own company
This is required for the system to create a production order instead of a purchase order.
5. What happens when the supplier is your own company
When the supplier is set to your own company:
The system creates a production order instead of a purchase order
The quantity is calculated automatically based on demand
The production is linked to the demand from parent products
6. How production is controlled
Production of semi-finished goods is automatically controlled by:
6.1 Demand from parent products
If a semi-finished good is included in a finished product:
Production of the finished product generates demand for the semi-finished good
ProdSys calculates the required quantity automatically
6.2 Inventory levels
Sufficient stock → no production
Shortage → production is suggested
6.3 Reservations and orders
Already reserved or ordered quantities are deducted from the demand
7. Example
Item: Ommramming (97716)
Stock: 1 pcs
Net available: -5 pcs
Suggested quantity: 5 pcs
If you select your own company as supplier:
→ ProdSys creates a production order of 5 pcs
8. Benefits
Automatic demand calculation (MRP)
Same interface for purchasing and production
Better control of semi-finished goods
Reduced manual planning
9. Tips
Use filters to show only items with demand
Verify delivery dates for correct planning
Review suggested quantities before creating orders
10. Summary
By using the purchase screen in ProdSys, you can:
Identify demand for semi-finished goods
Convert demand into production
Ensure correct inventory levels
All of this is automatically controlled based on actual demand in the system.
