**Tedarikçi Fiyatları** (Supplier Prices) is the master data that answers the question "at what price and in how
many days do we buy this item from this supplier". The agreed price in the record is brought to the order line as a
**proposal**; the user can change it. A decision made in a request for quotation automatically updates the winning
supplier's record. **Kaynak Listesi ve Kota** (Source List and Quota), on the other hand, determines per item which
suppliers it can be ordered from and how orders are split between suppliers.

| Field | Rule |
|---|---|
| **Ürün** (Item) | Mandatory; an active, purchasable card. |
| **Tedarikçi** (Supplier) | Mandatory; an active card with the supplier role. The same item–supplier pair cannot be defined twice ("Mevcut kaydı düzenleyin." (Edit the existing record.)). |
| Tedarikçi ürün kodu · tanımı (Supplier item code · description) | Optional. |
| **Anlaşmalı birim fiyat** (Agreed unit price) | Optional; cannot be negative. If a price is entered, **Fiyatın birimi** (Price unit) and **Para birimi** (Currency) are mandatory (and vice versa). |
| **Fiyatın birimi** (Price unit) | A unit defined in the card's unit conversions. If the order line is in another unit, the proposal is converted using the card's conversion. |
| Para birimi (Currency) | Three letters (TRY, USD, EUR). If the order's currency is different, the price is not proposed. |
| Asgari sipariş miktarı (Minimum order quantity) | Greater than zero. |
| Termin (gün) (Lead time (days)) | 0 or more. |
| Geçerlilik başlangıcı · bitişi (Valid from · to) | The start cannot be after the end. |
| Not (Note) | Optional. |
| **Ana tedarikçi** (Main supplier) | There is one main supplier per item; when selected, the previous main supplier is cleared automatically. |
| **Bloke kaynak** (Blocked source) | This item is not ordered from this supplier; the record and price history remain. A reason is mandatory. A main supplier cannot be blocked. |

**Fiyat Geçmişi** (Price History) shows the price evidence of the record with its document: goods receipt (`MK-…`,
actual purchase), service receipt (`HK-…`) and quotation decision (`TKL-…`, agreed price). The evidence of a reversed
receipt is marked and is not included in the last purchase calculation.

## Where the price comes from and where it goes

- **Order form:** When the item and supplier are selected, the agreed price is proposed as the **Birim Fiyat** (Unit
  Price) in the line's unit.
- **Quotation decision:** The discounted net price and lead time of the winning quotation become the agreed price.
  Example: after the TKL-2026-000001 decision, the HAM-0001 / T-0001 record was updated from 1,150.00 to
  **1,115.50 TRY**, and the lead time to 5 days.
- **Goods receipt:** The **Son Alış** (Last Purchase) information is updated.
- **Talep Kaynak Ataması (Requisition Source Assignment):** The price of the draft order line comes from here.

## Source List and Quota

**Satın Alma › Kaynak Bulma › Kaynak Listesi ve Kota** (Procurement › Sourcing › Source List and Quota)
(`/erp/procurement/sourcing`)

![Source list and quota](https://erpdocs.corexlogic.com/en/en/img/screens/satin-alma/kaynak-listesi.png)
1. Next source — server proposal
2. Source list required
3. Quota arrangement
4. Save

When an **Ürün** (Item) is selected:

- The **Kaynaklar** (Sources) table shows the item's supplier price records: Tedarikçi (Supplier), **Durum** (Status;
  Ana (sabit kaynak) (Main (fixed source)) · Kullanılabilir (Available) · Bloke (Blocked)), Fiyat (Price), Termin
  (Lead Time), Kota (Quota), Oran (Ratio). At the top is **Sıradaki kaynak** (Next source) — the supplier the system
  proposes for the next order (quota, main supplier or single source).
- **Kaynak listesi zorunlu** (Source list mandatory): If selected, the item is ordered only from a supplier that has
  a record and is not blocked; an order with a supplier without a record is rejected with the message "'X' için
  kaynak listesi zorunlu — tedarikçi listede yok …" (A source list is mandatory for 'X' — the supplier is not in the
  list …).
- **Kota düzenlemesi** (Quota arrangement): Valid from and to, a **Kota** (Quota; 0–100) per supplier and a
  **Başlangıç miktarı** (Starting quantity). The next order goes to the smallest ratio: (allocation + starting
  quantity) ÷ quota; the allocation is calculated in the base unit from orders submitted for approval or finalized
  within the quota window. A supplier appears only once in the quota, and at least one quota must be greater than
  zero.

**Kaydet** (Save) saves the rules (`erp-procurement-sourcing.edit`).
