IBM Maximo · Materials · Mobile 9.2
From the item master to a technician's phone in the field — how a material moves through planning, reservation, receiving, and issue, and what that whole journey looks like inside the Technician mobile app.
1 · What "Materials" Really Means in Maximo
"Materials" isn't one single thing in Maximo — it changes shape depending on where you are in the process. The same item can be something you're merely planning for, something a storeroom has physically set aside, something a supplier just delivered, or something a technician just consumed. Each of these is tracked as its own record, so nothing gets double-counted and everything stays auditable.
Planned
What you expect to need — defined on a work order before work begins.
Reserved
Inventory quantities earmarked for a specific job — spoken for, but not yet handed over.
Received
Materials that physically arrived into a storeroom (or straight to a work order).
Used
Materials actually issued to a work order, asset, or technician.
One Item, Several Lives A single part number — say, a pump seal — can be planned on a work order, reserved in the storeroom, and eventually issued, all while being the exact same catalog item throughout. What changes is which record represents it at each stage.
2 · Item Master & Inventory — Where Materials Live
Before It's Stocked: The Item Master
Every material starts life as an Item in the catalog — the master list of everything Maximo knows how to track, whether or not any of it is currently on a shelf.
| Item Type |
What It Means |
| Item |
A standard stocked part — the vast majority of what you'll manage |
| Tool |
Equipment that gets used and returned rather than consumed |
| Rotating |
A serialized asset tracked individually (e.g. a specific pump or motor) rather than as an interchangeable quantity |
Items can be built from other items — a Bill of Materials that's useful for kits and assemblies — and linked to one or more vendors, with a primary vendor driving default pricing and purchase order creation.
Once It's Stocked: Inventory
An inventory record ties an item to a specific storeroom at a specific site — the same item at two different sites is tracked as two completely independent balances.
Available Balance, Plain and Simple Available Balance = What's on the shelf − what's already spoken for (hard reserved, soft reserved, or expired). This is the number Maximo actually checks before letting you issue or reserve something — not the raw current balance.
A storeroom is just a location flagged as a storeroom, and it carries the GL account pointers used whenever a financial posting happens against it. Two special locations round out the picture: a holding location (exactly one per site, used as a waypoint when stock moves between sites) and a staging bin (a temporary spot for materials being inspected or sorted before they're put away). Reorder points and max levels on the inventory record can also trigger purchase requisitions automatically once stock runs low.
3 · Materials on Mobile: The Technician App
Separate from the standalone Material Request app we covered previously, the Technician App is where a field worker actually manages materials and tools while working a job. Here's every type they'll encounter, in the order they show up on the job — then we'll go deeper into the backend concepts behind each one.
A work order's details page — materials and tools live behind Report work button.
3.1 · Planned Materials & Tools Read-only
What the planner lined up shows up in two places: a top-level Materials & Tools page that aggregates planned items across all of a technician's assigned work orders, and a sliding drawer on the individual work order's details page. Neither is editable — they're purely informational. Selections made on the aggregate page persist across navigation, which is handy for pre-staging exactly what to physically carry out to a job site.
3.2 · Getting Reserved Items Action required
Items the storeroom has already set aside need to be confirmed before they count as used. The two sub-types are handled a little differently:
The materials action menu — get reserved items, asset spare parts, add items, or add materials.
Reserve Materials page — split into non-rotating and rotating sections.
| Type |
How Confirmation Works |
| Non-rotating items |
Select one or more, optionally adjust the quantity, tap Confirm. Multi-select supported. |
| Rotating assets |
Select the item, then choose the specific asset (serial number). Quantity is always 1 per asset and can't exceed what's reserved. |

Confirm
Confirming immediately creates a materials-used record — no separate manual entry needed.
3.3 · Recording Actual Materials Used Technician records
What was actually consumed or returned on the job, logged on the Report Work page. There are two ways to add a line:
Add items — for materials that are already in the catalog.
| Method |
When to Use It |
| Add items |
The material is a known catalog item — look it up, pick a storeroom and bin, enter quantity |
| Add materials |
A free-form line for anything without an item number — a field purchase or one-off consumable — with a description and unit cost typed in directly |
The Add Item drawer — storeroom and bin fill in automatically.
Both create a proper materials-used record, marked as an Issue or a Return. This works offline too — entries queue locally and sync once the device is back online.
The same page after two materials have been logged.
3.4 · Asset Spare Parts — The Shortcut Asset-driven
Rather than searching the full item catalog, a technician can pull up the specific asset they're servicing and see its manufacturer-recommended or storeroom-linked parts list, with live stock levels shown alongside. Select what's needed (capped automatically at what's actually available) and confirm — it's added straight to Materials Used. Mid-flow, the technician can switch to a different asset without leaving the page.
3.5 · Actual Tools Used Technician records
Tools are a parallel idea to materials, but tracked separately — a tool is used and returned, not consumed, so it creates its own kind of transaction rather than debiting inventory the way a material does.
| Drawer |
When It's Used |
| Standard |
Regular work orders — tool, storeroom, optional rotating asset, hours |
| Calibration |
Calibration work orders — adds traceability fields like manufacturer lot, solution type, due/use/expiry dates |
Qualification Check When a tool is selected, the app checks whether the technician is actually qualified to use it, and shows a warning before saving if not — a nice safety net baked right into the flow.
3.6 · Requesting Material When Stock Is Missing Cross-app feature
When something needed isn't available, the Technician App hands off to the Material Request app rather than duplicating that whole workflow. Existing requests tied to the work order show up in a "Requested material status" list — tap one to open it in the MR app. A cart icon starts a brand-new request, pre-filled with the work order, asset, and location, exactly like we covered in our earlier Material Request post.
4 · Planned vs. Reserved — Before It's Actually Used
Planned Materials
When a work order is created, a planner can specify exactly which materials the job will need — before the technician ever sees it. These planned materials capture the expectation: item, quantity, preferred storeroom, and whether the line should come from the storeroom or be purchased directly for that job. Once the work order closes, these lines lock and become read-only.

Reserved Materials
When a storeroom line is approved, Maximo creates a reservation — a formal hold that reduces available balance without yet touching the physical shelf count. We covered the soft-vs-hard distinction in detail in our Material Request post; the short version: a soft reserve is an intention, a hard reserve is a commitment that actually protects the stock.
What's worth adding here is the reservation's own lifecycle:
PENDING → ISSUED → COMPLETED or PENDING → CANCELLED
A reservation closes itself automatically once the full reserved quantity has been issued — partial issues are fine, the reservation just stays open until it's satisfied or cancelled. Two constraints worth knowing: the storeroom on a reservation can't be changed once it's created, and reservations only ever link to internal purchase orders.
5 · Receiving, Issuing & the Audit Trail
Receiving happens in core Maximo, not on mobile — it's included here only for context, since it's where the materials a technician eventually consumes actually come from. When goods arrive against a purchase order, storeroom balance goes up, cost is recalculated, and any open reservation it satisfies moves forward — all before a technician ever sees the item.
Issuing is the technician-facing half: removing stock from a storeroom and handing it to a work order or asset, whether through a reserve item, or a return. One exception worth knowing: rotating (serialized) items can't be issued to more than one asset at a time and don't use lot tracking, since each one is tracked individually rather than as a quantity.
Every movement, a receipt, an issue, a return — writes a permanent record to Maximo's transaction ledger. Nothing is ever edited after the fact; corrections happen through a new offsetting entry, which is what makes the ledger trustworthy as an audit trail.

6 · How Materials Get Costed
Material costs like Average, Standard, FIFO, or LIFO — are all calculated in core Maximo, not on mobile. A technician doesn't configure or see any of this; the cost simply reflects correctly on the transaction the moment a material is issued.
7 · Three Common Scenarios, Start to Finish
Scenario A — Planned Material, Storeroom Issue
WO Created
→
WO Approved
→
Stock Reserved
Storeroom Issues Material
→
WO Closed
Reservation status moves to Completed; final material cost rolls up to the work order.
Scenario B — Direct Purchase for a Work Order
WO Line Marked "Direct Requirement"
→
PO Raised
→
Received Straight to WO
No storeroom involved at any point — cost posts directly to the work order.
Scenario C — Material Request from a Field Technician
Technician Creates MR
→
MR Approved
→
Issued (in stock) or Procured (not in stock)
Covered in full in our Material Request post — this is the path when something's needed that wasn't on the original plan.
8 · Common Questions
What's the difference between "Reserved" and "Materials used" on my phone? Reserved means the storeroom has set it aside for you, but you haven't confirmed receiving it yet. Confirming a reservation is exactly what turns it into a materials-used record — that's the moment inventory and the work order cost actually update.
Why do tools create a different kind of record than materials? Because tools aren't consumed — you use them and give them back. Materials debit inventory permanently; tools just log who used what, for how long.
I can't find an item in the catalog to add — what now? Use the free-form "Add materials" option for line material, or raise a Material Request if it actually needs to be ordered in.
9 · Tips by Role
For First-Time Technicians
1
Check Planned Materials & Tools before heading to the site — know what's already expected.
2
Confirm reserved items promptly once you have them, so the record stays accurate.
3
Use Asset Spare Parts as a shortcut instead of searching the full catalog.
4
Always review the Safety Plan before starting work on a job that has one.
For Developers
Each mobile material and tool action is gated behind its own permission, so visibility can be controlled precisely by role. The Material Request hand-off from the Technician App is a shell-level app switch rather than an in-app page navigation — useful context if you're customizing either app.
10 · Wrap-Up
From the moment an item is first defined in the item master to the moment a technician taps "confirm" in the field, a material passes through a lot of hands — planned, reserved, received, used, and costed — each represented by its own record so the whole journey stays traceable. And with the Technician App, a field worker now touches almost that entire journey right from their phone, whether they're grabbing something already reserved, logging a spare part, or acknowledging a hazard before they even pick up a tool.
