Understand how automatic material reservation in IFS ERP optimizes inventory allocation across warehouses, remote locations, and production lines — reducing planner workload and ensuring production continuity at DH Pace.

In IFS ERP, efficient material reservation is critical for keeping production on schedule and orders fulfilled. At DH Pace, Auto Reservation automates the process of allocating available inventory to Shop Orders, Customer Orders, and Work Orders — eliminating manual effort and ensuring the right materials are reserved from the right locations at the right time.

This guide covers the complete workflow of material reservation in IFS ERP, including warehouse concepts, reservation priorities, remote warehouse handling, part control checks, and the business rules that drive DH Pace's inventory strategy.

Understanding Warehouses in IFS ERP

What is a Warehouse?

In IFS ERP, a Warehouse is a logical and physical inventory unit used to store, manage, reserve, pick, issue, and receive parts. It represents where inventory exists and how it can be used in business processes such as sales, manufacturing, projects, and maintenance.

Where stock is physically stored
Identified by a unique Warehouse ID
Linked to a Site for organizational context

What is a Remote Warehouse?

A Remote Warehouse manages inventory that is not physically present in the main warehouse but is still part of the supply chain. It is created in the Warehouse Navigator by checking the Remote option when setting up a new warehouse.

Service Vans — Mobile warehouses for field operations
External Storage — Third-party logistics (3PL) facilities
Partner-Managed Stock — Inventory at partner locations

Shop Order Creation Workflow

At DH Pace, automatic Shop Order (SO) creation is triggered when a Customer Order (CO) containing a manufactured part is released. This ensures customer demand is instantly converted into production demand based on predefined planning and manufacturing parameters.

1

Create Customer Order

Create a CO and add a CO line using supply code as 'SO' with the quantity and part number for a manufactured part (not a purchased part).

2

Release the Customer Order

Releasing the CO automatically creates the Shop Order based on the given parameters.

3

Shop Order Created

The SO is created automatically, and when reserving material it uses the demand code for an inventory part number instead of the manufactured part.

How Auto Reservation Works

What is Auto Reservation?

At DH Pace, Auto Reservation is the process where IFS ERP automatically allocates available inventory to a Shop Order's material requirements. Instead of manually reserving stock, the system checks all eligible warehouses, locations, and rules to decide where to pull materials from. This ensures production can start without delays and reduces planner workload.

How to Perform Auto-Reservation

Prerequisites: Auto reservation is only possible when the Shop Order is in Released status or higher.
Navigate to Shop Order: Open the Shop Order window in IFS Applications and go to the Material tab.
Select Reservation Method: Each material line has a Reserve/Issue Method (Manual, Automatic, or Backflush) specifying how the system will reserve materials.
Run Auto-Reservation: The system checks available stock across defined warehouses and reserves the needed quantities according to reservation parameters.
Pick List & Issuance: Once material is reserved, a pick list is generated for warehouse staff showing reserved quantities with a pick number.

Enabling Auto Reservation

In IFS Cloud, auto reservation is enabled inside the Site page under Warehouse Management → Auto Reservation tab. Materials are reserved based on the following priority rules:

Highest Put Away Zone Ranking

Determines which zone should receive incoming material first when stock is received.

Earliest Expiration Date

Materials with the closest expiry date are used first (FEFO logic).

Earliest Receipt Date

Stock received earliest is prioritized for reservation (FIFO logic).

Largest Quantity on Handling Unit

Prefers the handling unit containing the largest available quantity of the required part.

Reservation Locations in IFS ERP

IFS ERP can reserve materials from different location types. These locations represent logical or physical zones in the warehouse where stock is staged, consumed, or dispatched.

Picking Location

Primary location for order fulfillment. The most common reservation point for customer orders.

Floor Stock

Materials kept directly on the shop floor for immediate use in production, stored at or near the production area.

Production Line

Groups machines, work centers, and labor. Executes operations like cutting, welding, painting, and assembly.

Shipment Location

Staging area for goods ready to ship — the final inventory point before goods leave the site.

Remote Warehouse Reservation Logic

DH Pace Custom Logic

For DH Pace, the reservation logic is customized when material is reserved from a remote warehouse. The system ignores all part control checks and instead follows available locations and available quantity to reserve the material directly.

How Remote Warehouse Reservation Works

IFS checks available locations and quantity from the Reserve Backflush Availability box when a remote warehouse exists.
If material exists in a location, the system ignores Part Available Control for reserving.
The system checks Available Qty and Location Type only.
The following controls are ignored: Part Supply Control, Part Order Issue Control, Part Reservation Control, Part Manual Reservation Control, and Availability Control ID.

Where Remote Warehouses Fit in the Process

Step 1: Demand Creation

Customer Order, Shop Order, or Work Order triggers the process. System checks demand site, required part, quantity, and required date.

Step 2: Local Warehouse Check

System checks picking locations and shipment locations in local warehouses first.

Step 3: Remote Warehouse Eligibility

If local stock is insufficient, the system checks remote warehouse eligibility.

Step 4: Inter-Site Transfer

Automatically creates an Inventory Order or Distribution Order to pull from the remote location.

Reservation Dimensions

When reserving from remote warehouses, the system can reserve at multiple levels of granularity:

Warehouse — From a specific warehouse
Location — From a specific storage location
Lot / Batch — From a specific production batch
Serial Number — Individual serialized units

IFS Standard Flow & Part Control Checks

When reserving material from a warehouse using the IFS standard flow, the system enforces part availability controls to ensure proper inventory governance.

Part Control Checks (Standard Flow)

Unlike remote warehouse reservations, the standard flow enforces these controls:

Part Supply Control — Nettable or Not Nettable designation
Part Order Issue Control — Governs how parts are issued
Part Reservation Control — Must be set to Auto Reservation
Part Manual Reservation Control — Manual override settings
Availability Control ID — Defines availability rules

Standard Reservation Logic

Follows setup rules for expiration date, warehouse existence, and part reservation control.
Configures warehouse and location type (Picking, Floor Stock, Production Line, Shipment) and site.
Pulls from inventory based on available quantity and location.
Handles condition codes — reserves with or without a specified condition code.
Prefers the largest available quantity of the required part.

Key Business Rules for DH Pace

Auto-reservation in IFS ERP for DH Pace ensures efficient inventory management, compliance, and customer satisfaction. These rules align with DH Pace's operational needs in managing large-scale projects and security hardware distribution.

Demand Priority

DH Pace defines a fixed priority order for auto reservation to protect revenue and production commitments:

Priority 1: Customer Orders (external revenue)
Priority 2: Shop Orders (production continuity)

Demand Status

Auto Reservation is allowed only after demand is released to avoid premature inventory blocking:

CO Released
SO Released
WO Released

Part Supply Control

At DH Pace, part supply control governs which orders can use auto reservation:

Inventory Orders allowed
Shop Orders use manufactured parts
Customer Orders use manufactured parts

Warehouse Selection

DH Pace controls inventory ownership and logistics cost through warehouse hierarchy:

Primary Source: Main Warehouse
Secondary Source: Remote Warehouse

Cross-warehouse reservation follows site and ownership rules based on business approval.

Reservation Ranking (FIFO)

When multiple stock options exist, DH Pace applies the FIFO (First In, First Out) rule for reserving materials. This optimizes warehouse efficiency, reduces waste, and ensures older stock is consumed first to maintain compliance and quality standards.

Benefits of Auto Reservation for DH Pace

Improved Inventory Accuracy

Auto-reservation rules like FIFO and expiry-based allocation reduce waste and ensure compliance. Accurate stock levels are maintained across multiple warehouses and sites, preventing double-booking or over-reservation.

Efficiency in Order Fulfillment

Critical for DH Pace's construction and security hardware business where project timelines are strict. Eliminates delays caused by manual reservation processes.

Supply Chain Integration

Seamless integration between local and remote warehouses ensures material availability across the entire supply chain network.

Compliance & Traceability

Lot/Batch and serial number tracking ensure full traceability. Date-based reservations and priority handling support regulatory compliance requirements.
