How to Post a Vendor Invoice with MIRO in SAP S/4HANA

Open the MIRO transaction

Type miro in the SAP command field and press Enter. SAP opens the Enter Incoming Invoice: Company Code screen, with the relevant company code shown in the title bar.

Enter the company code and invoice header data

Select or confirm your Company Code (for example, 2000 – SOM Distilleries Pvt Ltd Sehatganj). Then fill in the main header fields:

• Invoice date: the date you're booking the invoice (e.g., 09.10.2022)
• Posting date: usually the same as the invoice date
• Amount: the invoice amount as per the vendor bill
• Reference: optional — any reference number from the invoice
• Text: optional — any relevant notes

Check that the Balance field at the top reads zero before you continue.

Select the source document for the invoice

Open the PO Reference tab and choose which type of source document the invoice is based on:

• Purchase Order/Scheduling Agreement
• Delivery Note
• Bill of Lading
• Service Entry Sheet
• Supplier
• Transportation Service Agent
• Exchange Agreement (IS-Oil Only)

Purchase Order/Scheduling Agreement is selected by default, but you can change it depending on your invoice source.

Confirm the reference type

You can book the invoice using any of the available reference types, depending on your business process. Enter the Purchase Order Number or select another reference type that matches your invoice source.

Select Purchase Order/Scheduling Agreement as the reference

With Purchase Order/Scheduling Agreement selected in the PO Reference tab, SAP pulls in all related material and quantity details once you provide the purchase order number.

Enter the purchase order number

Type the Purchase Order Number (for example, 1400019044) in the field next to the reference type, then press Enter. SAP fetches the purchase order and displays all of its associated materials and quantities.

Verify the populated purchase order details

Confirm that the Amount (e.g., Rs. 24,400) and Quantity (e.g., 1 SET) shown in the item overview are correct. The Balance field at the top should reflect the invoice amount (e.g., 24,400.00 INR), and the material description (e.g., FIXING HARDWARE FOR BODY LINER) should appear in the item text.

Enter the baseline date

If prompted, enter the Baseline Date used for payment calculation — typically the current date. Use the calendar popup to select the date (e.g., 09.10.2022), then press Enter to confirm.

Review the purchase order conditions

Double-click the purchase order line to open its detailed view, then go to the Conditions tab. Check the pricing elements to confirm the invoice amount matches the purchase order (for example, Gross Price = 24,400.00 INR), and review any discounts, taxes, or additional charges listed.

Confirm consistency between the PO and the invoice

Make sure the amount shown in the Conditions tab (e.g., 24,400.00 INR) matches the amount entered in the MIRO invoice entry. Once the figures align, return to the MIRO screen to continue.

Enter the tax amount

Tick the Calculate Tax checkbox if applicable, and enter the Tax Amount (e.g., 4,392) in the relevant field. SAP updates the total amount and shows any resulting difference (e.g., total difference = 28,792).

Review the invoice entry screen

The Enter Incoming Invoice: Company Code 2000 screen displays tabs for Basic Data, Payment, Details, Tax, and Withholding tax, with the PO Reference, G/L Account, and Material tabs at the bottom. Confirm the header shows transaction type "Invoice" and the correct supplier code.

Key fields to check:

• Invoice date: 09.10.2022
• Posting date: 09.10.2022
• Amount: 28,792.00 INR
• Tax Amount: 4,392.00
• Payment terms: Due immediately
• Baseline date: 05.08.2022
• Purchase order: 1400019044
• PO text: FIXING HARDWARE FOR BODY LINER

The PO item shows an amount of 24,400.00 and a quantity of 1 SET. You may see a note that the net due date is in the past — this is informational and doesn't prevent posting.

Check the balance indicator

Look for the green indicator next to the Balance label at the top of the screen. It confirms the balance status of your entry, which should read 0.00 INR once the amounts are correctly matched.

Enter the invoice amount and tax amount

Under Basic Data, confirm the Amount field holds the invoice value (e.g., 28,792.00 INR) and the Tax Amount field holds the correct tax figure (e.g., 4,392.00). The PO item amount (e.g., 24,400.00) should correspond to the goods or services received.

Verify amount consistency

Confirm that the amount entered in the invoice matches the amounts in your GRIR (Goods Receipt/Invoice Receipt) and MIRO records. SAP requires these figures to match before you can post the invoice.

Ensure the balance is zero before posting

Check that the Balance field at the top reads exactly 0.00 INR. If it doesn't, you can't proceed to post the invoice — adjust the amounts as needed until the balance reaches zero.

Simulate the document

Click Simulate in the toolbar (tooltip: Simulate Document, Ctrl+Shift+F7) to preview the accounting entries before you post the invoice.

Enter reference information

In the Reference field, enter the invoice number or another relevant reference (e.g., 432) for tracking and audit purposes. You can also add the same reference in the Text field if required.

Review all entered details

Before proceeding, double-check:

• Quantity (e.g., 1 SET)
• Amount (e.g., 24,400.00)
• Balance (should read 0.00 INR)
• Supplier details (e.g., Supplier 0000040300)

Make sure every detail matches the physical invoice and the purchase order.

Re-simulate if you made changes

If you changed any values, click Simulate again to confirm the balance stays at zero and all entries remain correct. This step helps you avoid posting errors.

Review the debit and credit entries

Clicking Simulate opens the Simulate Document in INR (Document currency) window. Review the entries:

• The first line (G/L account 1190020) shows a debit of 28,792.00 INR
• The second line (G/L account 1240080, GRIR Cfg-Spare Parts D) shows a credit of 28,792.00 INR
• The Purchasing Document column references PO 1400019044, item 10
• The Tax Code column shows "GF"
• The balance at the bottom reads 0.00, confirming the entries are balanced

Confirm every value matches your invoice and purchase order, including the tax code and tax date.

Post the invoice

Once the debit and credit amounts are equal and the balance reads 0.00, click Post at the bottom right of the simulation window to finalize the invoice entry in SAP.

Reconfirm entry details if corrections are needed

If you're prompted to make corrections, return to the main invoice entry screen and verify these fields:

• Invoice date: 09.10.2022
• Posting date: 09.10.2022
• Amount: 28,792.00 INR
• Reference: 432
• Tax Amount: 4,392.00
• Text: 432
• Payment terms: Due immediately
• Baseline date: 05.08.2022
• Purchase order: 1400019044
• PO text: FIXING HARDWARE FOR BODY LINER

Adjust any field as necessary before posting.

Confirm the entry

After verifying all details, press Enter to confirm the data. SAP validates your entries and prepares them for posting.

Review the purchase order history

Open the Purchase Order History tab in the purchase order display (transaction ME23N) to review related transactions, including delivery costs, goods receipts, invoice postings, and down payments. Check the amounts, posting dates, and document numbers, and confirm the invoice amount (e.g., 28,792.00 INR) is reflected correctly.

Analyze the goods receipt event

In the purchase order history, find the line with movement type 105 (Goods Receipt). Review its material document number, posting date, quantity, and amount to confirm the goods receipt and invoice postings are properly linked.

Return to the invoice entry screen

After reviewing the purchase order history, go back to the invoice entry screen to continue or finalize the process.

Post the invoice after simulation

With the simulation and review complete, click Post to finalize the invoice entry. SAP processes the posting and updates the relevant ledgers.

Confirm the data is saved

After posting, SAP displays a confirmation message that the data has been saved, along with a document number shown at the top of the screen. The invoice is now officially recorded in SAP.

Review the final invoice entry

On the finalized Enter Incoming Invoice: Company Code 2000 screen, confirm the balance at the top reads 0.00 INR and the key fields show the posted values:

• Invoice date: 09.10.2022
• Posting date: 09.10.2022
• Amount: 28,792.00 INR
