# Failed backflushes

> The queue of components that could not be backflushed at output — causes, Retry and Close; an open record blocks completion of the order.

**Backflush** (geri sarf) means that a component flagged in the BOM is issued automatically **together with the
output**, without a separate consumption posting (small materials such as screws, rivets, labels). If a component
cannot be issued when output is posted, **the output is not reversed**; the component goes into this queue and waits
until it is resolved.

- **Module:** Manufacturing
- **Menu path:** Üretim › Üretim Yürütme › Hatalı Geri Sarflar (Production › Production Execution › Failed Backflushes)

- **Required permission:** `erp-manufacturing-postings.view (liste) · .create (Yeniden Dene)`, `erp-manufacturing-corrections.create (Kapat)`

![Backflush Errors — open record](https://erpdocs.corexlogic.com/en/en/img/screens/uretim/geri-sarf-listesi.png)
1. Order whose output was posted
2. Error — why the backflush failed
3. Retry — with another warehouse or stock status
4. Close — with a reason, no consumption

## How backflush works

- Quantity to issue = planned quantity of the requirement × (total produced ÷ planned quantity of the order) − quantity
  consumed so far (rounded up to the precision of the unit). Manual consumption is not counted twice. Example: on
  **UE-2026-000008**, planned for 2 ADET (pieces), the leveling foot requirement is 8 ADET; 1 ADET output, no
  consumption → **4 ADET** backflushed.
- The component is issued from the **Geri sarf deposu** (Backflush warehouse) **in the output form**; if it is left
  blank, the warehouse of the first output line is used. If the stock status is blank, the default status (SIFIR, new).
- A batch-managed component is issued with the FEFO proposal. A component without batch management: if the warehouse
  requires a storage location, from the item's **default storage location** in that warehouse; otherwise from stock
  **without a storage location**.
- A serial-number-managed component is not backflushed; it must be consumed manually.
- A successful backflush is recorded as a separate **material consumption document** on the order's **Malzeme
  Sarfları** (Material Consumptions) tab.

> **Watch out for stock in storage locations**
If the component's stock is in a storage location and the backflush warehouse does not require storage locations, the
backflush looks at stock without a storage location and returns a "yeterli stok yok" (insufficient stock) error. Either
define a **default storage location** in the item's warehouse data, or issue the component manually with a
[material consumption](https://erpdocs.corexlogic.com/en/uretim/islemler/malzeme-sarfi-kaydetme) and close the record with a reason. In the demo
example, HAM-0049 was in HAMMADDE / RAF-C; the backflush reported "Mevcut: 0" (Available: 0).

## Columns and filters

| Column | Meaning |
|---|---|
| **Üretim emri** (Production order) | The order whose output was posted and the output date. |
| **Bileşen** (Component) | The item that could not be issued. |
| **Miktar** (Quantity) | The quantity that must be issued. |
| **Hata** (Error) | The server's reason, verbatim (e.g. "'HAM-0049' kartının 'SIFIR' durumunda yeterli stok yok. Mevcut: 0, istenen: 8,000000." — Insufficient stock of item 'HAM-0049' in status 'SIFIR'. Available: 0, requested: 8.000000.). |
| **Durum** (Status) | **Açık** (Open), **Çözüldü** (Resolved) or **Kapatıldı** (Closed). |

- The **Durum** (Status) filter defaults to **Açık** (Open; the work queue); **Tümü** (All) also brings resolved and
  closed records.
- **Sorumlu olduğum iş merkezleri** (Work centers I am responsible for) shows only orders of the work centers you are
  responsible for.
- The "bu emrin hatalı geri sarfları" (failed backflushes of this order) link in the order details narrows the list to
  that order (**Tek emrin kayıtları**, Records of a single order).
- Records are not created on this screen; they arise only from output.

## Retry

![Retry Backflush dialog](https://erpdocs.corexlogic.com/en/en/img/screens/uretim/geri-sarf-yeniden-dene.png)
1. Warehouse to issue the component from
2. Stock status (empty = recorded status)
3. Retry — consumption posted, record resolved

If stock has arrived, or the component is to be issued from another warehouse, use **Yeniden Dene** (Retry): the
window shows the last error, and you select the **Depo** (Warehouse) and **Stok durumu** (Stock status). If it
succeeds, a consumption document is posted, the record becomes **Çözüldü** (Resolved) and the message "Bileşen sarf
edildi — kayıt kapandı." (Component consumed — record closed.) appears. If it fails, the error is shown in the window
and the record stays open.

## Close

**Kapat** (Close) does not post consumption; it closes the record with a reason (**Hatalı Geri Sarfı Kapat — kart**
(Close Failed Backflush — item) window, **Gerekçe** (Reason) required, at most 500 characters). Use it if you consumed
the component manually or if the component was actually not used. A closed record cannot be retried. Example reason:
"Bileşen RAF-C lokasyonundan elle sarf edildi." (The component was consumed manually from storage location RAF-C.)

> **An open record prevents closing the order**
If the order has an open failed backflush, **Tamamla** (Complete) is rejected: "Emirde çözülmemiş 1 hatalı geri sarf
var — tamamlamadan önce yeniden deneyin ya da gerekçeyle kapatın: 'HAM-0049' 8 ADET — …" (The order has 1 unresolved
failed backflush — retry it or close it with a reason before completing: 'HAM-0049' 8 pieces — …)

## Common messages

| Message | English meaning | Cause |
|---|---|---|
| 'KART' kartının 'SIFIR' durumunda yeterli stok yok. Mevcut: …, istenen: … | Insufficient stock of item 'KART' in status 'SIFIR'. Available: …, requested: … | There is not enough stock in the selected warehouse/status (without storage location). |
| 'DEPO' lokasyon istiyor ve 'KART' kartının bu depoda varsayılan lokasyonu yok. | 'DEPO' requires a storage location and item 'KART' has no default storage location in this warehouse. | Enter a default storage location in the item's warehouse data. |
| 'KART' için depoda yeterli lot yok — eksik … | Not enough batches in the warehouse for 'KART' — missing … | FEFO was not sufficient for a batch-managed component. |
| 'KART' seri takipli — geri sarf edilemez, elle sarf edin. | 'KART' is serial-number managed — it cannot be backflushed; consume it manually. | Serial-number-managed component. |
| Yalnız açık hatalı geri sarf yeniden denenir. · Hatalı geri sarf zaten kapanmış. | Only an open failed backflush can be retried. · The failed backflush is already closed. | The record has been resolved or closed. |
| Kapatma gerekçesi zorunlu. | A closing reason is required. | The reason is blank. |
