Prerequisites
  • The output card is flagged "Üretim ürünü" (Production item) (semi-finished or finished product), is active and is not a service card.
  • The material cards are active and the units to be used can be converted to the base unit.

A bill of materials is the card's recipe. A saved BOM is created with a Taslak (Draft) revision; releasing it is a separate operation. If the card already has a BOM for this usage, the new BOM becomes the next alternative.

Steps​

  1. Open the Üretim › Ana Veriler › Ürün Ağacı Oluştur (Production › Master Data › Create BOM) screen or click Yeni Ürün Ağacı (New BOM) in the Ürün Ağaçları (Bills of Materials) list.
    Open screen/erp/manufacturing/boms/newExpected: The Yeni Ürün Ağacı (New BOM) form
  2. Type the card's code in the Çıktı Kartı (Output Card) field and press Enter, select the card from the list and press Enter again (F4 or the magnifier opens the list).
    EnterÇıktı KartıValue: MAM-0010Expected: The unit of the base quantity is filled with the card's base unit
  3. Enter the Temel Miktar (Base Quantity) and its unit. Line quantities apply to this output quantity (e.g. 1 ADET (pc) or 100 ADET).
    EnterTemel MiktarValue: 1
  4. If there is a loss of finished product in the process, enter the Montaj Firesi (%) (Assembly Scrap, %); all components are increased by this percentage.
    EnterMontaj Firesi (%)
  5. Select the Kullanım (Usage): Üretim (Production) for actual production, Mühendislik (Engineering) for the design phase. If necessary, enter an Alternatif adı (Alternative name) and Parti büyüklüğü (Lot size).
    SelectKullanımValue: Üretim
  6. Click Malzeme Ekle (Add Material), check the required cards in the window and add them; each card becomes a separate line. To enter by typing a code, use Boş Satır (Empty Line).
    ClickMalzeme Ekle
  7. On each line, enter the Miktar (Quantity) and Birim (Unit); if necessary, enter the Bileşen firesi (%) (Component scrap, %) and check Geri sarf (Backflush) for consumables to be deducted automatically with the output.
    EnterMiktarValue: HAM-0030 · 18 KG · fire 5 — HAM-0034 · 4 M — HAM-0049 · 4 ADET · geri sarf
    Create Bill of Material — completed form
    1. 1Output item — produced items only
    2. 2Base quantity — line quantities refer to it
    3. 3Usage — Production or Engineering
    4. 4Add Material — pick several items
    5. 5Component scrap (%)
    6. 6Backflush — consumed automatically with output
    7. 7Save — draft revision 1 is created
  8. If an equivalent card can be used, add an alternative with Ekle (Add) in the line's Alternatif (Alternative) column and select the Strateji (Strategy) (Öncelik (Priority) or Kullanım olasılığı (Usage probability)).
    ClickEkle
  9. If a by-product or co-product arises together with the order's output, add it with Yan / Ortak Ürün Ekle (Add By-Product / Co-Product).
    ClickYan / Ortak Ürün Ekle
  10. Click Ürün Ağacını Kaydet (Save BOM).
    ClickÜrün Ağacını KaydetExpected: The BOM detail opens; Rev. 1 Taslak (Draft), Yayınla (Rev. 1) (Release, Rev. 1) in the header
Result
The BOM is saved with draft revision 1 and its detail opens. A draft is not used in planning or on orders; to use it, release the BOM. In the demo environment, BOM #49 (Alt. 1 · Demo tasarım ağacı (Demo design BOM)) with Mühendislik (Engineering) usage was created for MAM-0010 with these steps.

What you need to know​

  • When the order is released, the requirement is scaled as satır miktarı × planlanan miktar / temel miktar (line quantity × planned quantity / base quantity); component scrap increases it by (1 + fire/100) (1 + scrap/100), and the result is rounded up to the unit's precision.
  • A card can appear in the BOM only once, either as primary or as alternative; the BOM's own output card cannot be a material.
  • For a serial-managed output, the base quantity must be an integer; for a serial-managed component, the material quantity must be an integer.
  • A backflushed component is consumed in the planned proportion when the output is posted; a serial-managed component is not backflushed.
  • Before saving, the form is validated on the server for item eligibility, unit conversion and cycles; if there is an error, the Ürün ağacı kaydedilemedi (BOM could not be saved) summary lists the incorrect fields.
  • If the output card is configurable, conditions and formulas are written on the lines: Conditions.
