MRBR: Release Blocked Invoices in SAP
Olivia Turner
⚡ Smart Summary
Release an Invoice in SAP using transaction MRBR. A blocked invoice cannot be paid until the block is lifted, and MRBR clears manual payment blocks as well as blocks raised by variance during invoice verification.
Why Invoices Get Blocked in SAP
Invoice verification compares three documents: the purchase order, the goods receipt, and the vendor invoice. When they disagree beyond the configured tolerance, SAP still posts the invoice but sets a payment block so money cannot leave until someone reviews it.
The block is therefore a control, not an error. Understanding which check raised it tells you whether releasing is appropriate or whether the underlying document needs correcting first.
| Block reason | What triggered it | Usual resolution |
|---|---|---|
| Price variance | Invoice price differs from the purchase order price beyond tolerance | Correct the order price, or accept and release |
| Quantity variance | Invoiced quantity exceeds the quantity received | Post the missing goods receipt, then release |
| Date variance | Delivery arrived later than the scheduled date | Review with the buyer, then release |
| Quality inspection block | Material is still in quality inspection stock | Complete the usage decision, then release |
| Manual payment block | A user set the block deliberately in MIRO | Release manually once the query is settled |
| Stochastic block | Random sampling selected the invoice for audit | Review and release; no document is wrong |
Quantity variance is the most common of the six and almost always means the goods receipt has not been posted rather than that the vendor over invoiced.
How to Release Blocked Invoices
An invoice request is blocked for payment until it is manually released. You can release the invoice by using t-code MRBR.
Step 1)
- Execute t-code MRBR.
- On the initial screen enter the company code and invoice number.
- Check the release method (release manually if you want to process it in the second screen). This can be done choosing Automatically (please note the difference with automatic release in MIRO transaction being blocked and automatic release in t-code MRBR as those are two different things).
- Our document has a manual payment block, so we will select that option. Execute.
Step 2)
- Select the invoice you want to release.
- Click on the flag icon – release.
You can see that now the invoice has Status field filled with green flag – it means, it is released to FI.
Financial department should now be able to see the invoice ready for payment.
Manual Release vs Automatic Release in MRBR
The selection screen offers two release methods and they behave very differently. Choosing the wrong one is why an expected invoice sometimes fails to appear in the worklist.
| Parameter | Release manually | Release automatically |
|---|---|---|
| What it does | Lists blocked invoices for the user to select and flag | Scans blocked invoices and clears those whose block reason no longer applies |
| User decision needed | Yes, per document | No, the system decides |
| Clears a manual payment block? | Yes | No, a manual block always needs a person |
| Typical use | Reviewing genuine price or quantity disputes | Nightly job after goods receipts have caught up |
| Run as background job | Not practical | Yes, this is the normal setup |
⚠️ Warning: Automatic release in MRBR and automatic blocking in MIRO are unrelated settings despite the similar names. Automatic release only removes a block whose cause has genuinely gone; it never overrides a manual payment block set by a user.
Invoice Verification Transaction Codes
MRBR sits at the end of the invoice verification chain. The table lists the transactions that surround it.
| Transaction Code | Purpose |
|---|---|
| MIRO | Enter an incoming invoice against a purchase order |
| MIR7 | Park an invoice for later completion or approval |
| MIRA | Background invoice verification for high volume processing |
| MIR4 | Display or change an invoice document |
| MIR5 | Display a list of invoice documents |
| MIR6 | Invoice overview with selection by status and block |
| MRBR | Release blocked invoices |
| MR8M | Cancel a posted invoice document |
| MR11 | Clear GR/IR account differences after the process closes |
Where the invoice itself is wrong rather than merely blocked, cancelling with MR8M and re-entering is cleaner than releasing and correcting afterwards. Where the purchase order carried the wrong price, fix it in change purchase order and update the purchase info record so the next invoice matches automatically. The wider process is mapped in the SAP MM tutorial series.
