# Issue material to an order (/docs/production/issue-material)

The store pulls material for a manufacturing order from stock. The default role is Store (Farah Hanim).
Open **Inventory > Material issue**. The list is called **Pick lists** and shows each order with
material to pick.

## Issue material to an order [#issue-material-to-an-order]

The system works out the quantity as bill-of-materials quantity times order quantity plus a 2% scrap
allowance. It only offers lots that are **Released**, not expired, with enough shelf life left, and
not customer consignment of another customer. Each item follows its picking rule. **FEFO** takes the
earliest expiry first and keeps the item's minimum days of shelf life at issue. **FIFO** takes the
oldest received lot first.

<Steps>
<Step>

Open the order, for example `MO-2026-1131`. The header reads "1 Acknowledge the task · 2 Start pull ·
3 Scan lots · 4 Issue". Choose **Acknowledge**. It records your name and the time. No stock moves yet.

</Step>
<Step>

At the bins, choose **Start pull**.

</Step>
<Step>

For each suggested lot, scan the lot label or type the lot number in **Lot code**, then choose **Scan lot**. The button stays off until a code is entered, and a lot that is not on the pick list is refused. The header
counts "\{n\} of \{total\} lots scanned". The table shows **Lot**, **Bin**, **Received**, **Expiry**,
**Left**, **Available** and **Pick**.

</Step>
<Step>

When every lot is scanned, choose **Issue to \{machine\}**. Lot quantities drop and an Issue movement
is posted for each lot, and the issue is signed in your name. The page reads "Material issued to \{order\}".

</Step>

## Skip a lot [#skip-a-lot]

If the suggested lot is damaged or cannot be found, choose **Skip**. The dialog reads "Skipping the
\{rule\} choice is a deviation. Reason *". Write the reason, for example "Container damaged, lot not
found in bin", and choose **Skip lot**. The system logs it and offers the next eligible lot.

## When there is not enough stock [#when-there-is-not-enough-stock]

A line that no lot can cover reads "Short \{qty\}. No other eligible lot in stock." Choose **Raise
requisition**. A purchase requisition is made, needed in seven days, and the line shows "\{pr\} raised".
The pick stays open: you can **Issue available to \{machine\}** for what is in stock, and issue the rest
later. Planning is told about the shortage.

## Return unused material [#return-unused-material]

<Steps>
<Step>

Open the order. Under the issued lots, find the line. The columns are **Lot**, **Item**, **From bin**,
**Rule**, **Issued**, **Returned**, **Issued at** and **Return**.

</Step>
<Step>

Enter the quantity in **Return**, from 0 up to what is not yet returned, and confirm. The page reads
"\{qty\} returned to \{lot\}".

</Step>
</Steps>

The material goes back to the same lot and bin and keeps its received and expiry dates. The system
posts a Return movement.

## Block an expired lot [#block-an-expired-lot]

On the shelf-life screen, **Expired lots** are never offered on a pick list. Choose **Block lot** so
nobody moves or issues them by hand, then raise an NCR for disposal.

## If the system refuses [#if-the-system-refuses]

Messages shared by every flow are in
[Signatures and refusals](/docs/get-started/signatures-and-refusals). Pick-list messages are in
[Planning refusals](/docs/production/planning-refusals#issue-material-to-an-order). Examples:

- `Acknowledge the task first.` and `Start the pull before scanning lots.`
- `{lot} is not on the pick list for {item}.`
- `{n} of {total} lots scanned. Scan every lot before issuing.`
