Account-Assigned Purchase Order (K — Cost Center, F — Order): Consumption at Goods Receipt
Goods bought for direct consumption never become stock: the PO item carries an account assignment (cost center K, order F), the goods receipt posts the expense straight to that cost object, and the invoice clears GR/IR as usual.

01How should the PO item be set up?
Maintenance needs 20 bearing sets for one repair. They are not stocked. How should the PO item be created?
Business scenario
The maintenance department needs 20 bearing sets for a planned repair. They are not kept in stock, so purchasing orders them directly for cost center CC-4100.
All companies, numbers and documents are fictional demo data.
Step-by-step flow
- 01
How should the PO item be set up? open in twin
Maintenance needs 20 bearing sets for one repair. They are not stocked. How should the PO item be created?
K means cost center, F order, P project (WBS element), A asset — each needs the matching CO object on the item.
- 02
Consumables in stock open in twin
Without account assignment the bearings become valuated stock. Someone must later post a 201 goods issue to the cost center — an extra step that is often forgotten.
For items bought for one known consumer, stock is overhead: two postings and a period where the cost sits in inventory instead of with the consumer.
- 03
PO with account assignment K open in twin
PO 4500001500: 20 EA MRO-500 at ₹1,500, account assignment K, cost center CC-4100 (Maintenance).
Everything downstream (goods receipt and invoice) uses these to post the cost.
- 04
Goods receipt posts consumption open in twin
The bearings arrive and go straight to maintenance. GR posts ₹30,000 to cost center CC-4100 (Maintenance). Stock does not change.
The goods are for immediate use, so with a valuated goods receipt (as here) the cost lands with the consumer at the moment of receipt. With a non-valuated GR, the receipt updates only the quantity and posts no expense; the expense is generally posted at invoice receipt instead.
- 05
Invoice clears GR/IR open in twin
MIRO: GR/IR ₹30,000 against the supplier. The cost center already carries the cost.
Price differences on account-assigned items go to the account-assigned cost object.
- 06
Consumed, never stocked open in twin
Cost center CC-4100 (Maintenance) carries ₹30,000. Stock never existed.
With F (order), the same flow charges a production or maintenance order instead of a cost center.

Stock impact
This part of the process does not change stock.
Accounting impact
Goods receipt for an account-assigned PO item
TypicalGoods receipt posts consumption
- Dr Maintenance consumables — CC-4100 (Maintenance) (KBS (PO account))₹30,000
- Cr GR/IR clearing (WRX)₹30,000
The expense account and cost center come from the PO item, not from material valuation. Transaction key KBS marks the posting (typical); the G/L account itself is the one on the PO item.
Invoice for the account-assigned item
TypicalInvoice clears GR/IR
- Dr GR/IR clearing (WRX)₹30,000
- Cr Supplier 100001 (payable)₹30,000
Clears GR/IR as for any PO. A price difference would go to the cost center as well, not to inventory.
Typical conceptual flow. Actual G/L accounts and posting behaviour depend on material valuation, automatic account determination and system configuration.
Movement type

Common errors
“PO cannot be saved”
Likely causes: Cost center missing or locked; G/L account not a cost element; Account assignment category requires a field not entered
Where to look: PO item account assignment tab · Cost center master · OME9
“Cost appears at invoice instead of GR”
Likely causes: Non-valuated GR indicator set
Where to look: PO item delivery tab

CHECK 1
Posting
- Is the cost center open?
- Is GR valuated for this account assignment category?
Interview questions
What does goods receipt post for a PO item with account assignment K?
No stock. It posts consumption to the G/L account on the PO item with the cost center as CO object, against GR/IR — unless the non-valuated GR indicator is set, in which case the cost is posted at invoice.
Name common account assignment categories.
K cost center, F order, P project (WBS element), A asset, E/M sales order (for make-to-order or third-party). Each requires its own CO object on the PO item.
