# Serial combinations

## What serial combinations are

Serial combinations are configuration reference data for the company.
Use this configuration reference when you need to review the patterns used for company records.
The list is the starting point; selecting a row opens its configuration record.

| If you need to… | Go to |
|---|---|
| Review the available patterns | [Find and open a serial combination](#find-and-open-a-serial-combination) |
| Read the columns and configuration fields | [Understand the list and configuration fields](#understand-the-list-and-configuration-fields) |
| Add or change component rows | [Maintain a serial combination](#maintain-a-serial-combination) |
| Diagnose an unavailable list or control | [When the screen does not behave as expected](#when-the-screen-does-not-behave-as-expected) |

| Review product serial-combination settings | [Product serial combinations](doc:configuration-product-combination-view) |

## Before you start

Sign in before opening the **Configuration** area. Your account needs editing access to change a
serial combination. The configuration area also depends on the serial-combination feature being
included in your subscription.

The record must be available before you can maintain its rows. Open a saved record from its row in
the serial-combination list.

## Find and open a serial combination

A serial-combination list is the place to identify an existing pattern before you review or change
its component rows.

Prerequisites

- You are signed in.
- You know which serial pattern you need to review.

Steps

1. In **Configuration**, open **Serial combinations**.

   ![Review the empty serial-combination list and its **Name** and **Serial Combination** headers.](https://atloriaassets.blob.core.windows.net/assets/a438221c-c1af-407c-b9e6-a56c986db846/2968434f2f2d24a310749f39b53f6808.png)

2. Read the **Name** column to identify the serial type.

3. Read the **Serial Combination** column to review the displayed pattern.

4. Use the available search field when it is shown.

   ![Locate the list search area above the serial-combination grid.](https://atloriaassets.blob.core.windows.net/assets/a438221c-c1af-407c-b9e6-a56c986db846/72c22ff4a515ddda93727813238a4b70.png)

5. Select the row or its edit control to open the configuration record.

**Result:** The selected serial-combination record opens.

## Understand the list and configuration fields

The list summarizes each pattern, while the configuration record arranges its component rows in
the order used by the pattern.

The list contains these columns:

| Column | What it contains |
|---|---|
| **Name** | The serial type name from the lookup list. |
| **Serial Combination** | The generated pattern readout. |

The configuration grid contains these fields:

| Field | Control and rule |
|---|---|
| **Serial Component** | Select the component for the row. A component is required when the row is not empty. |
| **Digits** | Select the available digit count for the selected component. The field is shown only for components that use a digit count. |
| **Default Value** | Enter the default value for the selected component when **Default Value** is available. |

When the record has audit history, select **Last Modifications** to read the change history.

   ![Review the **Serial Component**, **Digits**, and **Default Value** columns in the configuration grid.](https://atloriaassets.blob.core.windows.net/assets/a438221c-c1af-407c-b9e6-a56c986db846/b3aabdc349ab3ed15e326a6288893e91.png)

The configuration record also contains an ordering area and an action area without text labels.
The list provides edit and reset actions as icons.

## Maintain a serial combination

Maintaining a serial combination means arranging its component rows so the displayed pattern uses
the intended order, component, digit count, and default value.

Prerequisites

- You have opened the serial-combination record.
- Your account has editing access.

Steps

1. Select **Component** to add a component row.

2. In **Serial Component**, select the component for the row.

3. In **Digits**, select the applicable digit count.

4. In **Default Value**, enter the value used by that component when the field is available.

5. Repeat steps 1 through 4 for each component row in the required order.

6. To remove an empty row, select its delete icon.

7. To remove a populated row, open the row's actions.

8. In the confirmation, read `Are you sure you want to delete this row?`.

9. Select **Cancel** to keep the row.

10. Select **Delete** to remove the populated row.

11. Select **Save**.

**Result:** The configuration record remains open with the component rows and pattern readout on
screen.

## Handle access branches and failures

Use this procedure to choose the available branch before changing a serial combination.

Prerequisites

- You have opened a serial-combination record.

Steps

1. Choose the action that matches what is on screen.

   | If you see… | Select… |
   |---|---|
   | The subscription-upgrade area | **Back** to return. |
   | **Save** and **Component** | [Maintain a serial combination](#maintain-a-serial-combination). |
   | The leave-page close action | The close action to leave without editing. |
   | When audit history is available | Select **Last Modifications** to read the change history. |

| Condition | What you see or use |
|---|---|
| The serial-combination feature is not included in the subscription | The subscription-upgrade area replaces the configuration area. |
| The feature is included | The configuration area is shown. |
| Editing access is available | **Save**, the close action, **Component**, and row edit or reset actions are available. |
| Editing access is unavailable | The leave-page close action is shown instead of the editable close action. |
| The selected component uses a digit count | **Digits** is available. |
| The selected component does not use a digit count | Continue with the fields that are shown for that component. |
| The selected component uses a default value | **Default Value** is available. |
| When audit history is available | **Last Modifications** and its history area are shown. |
| An exit popup appears | `` `Don't Save`, `Save`, `Cancel` `` |
| An import popup appears | `` `Cancel`, `Upload` `` |
| A confirmation popup appears | `` `No`, `Yes` `` |
| An alert popup appears | `Ok` is available. |
| The subscription-upgrade popup appears | `Back` is available. |

When the form validates a row, it can display these exact messages:

| Message | Reader action |
|---|---|
| `Component is required.` | Select a component in **Serial Component**. |
| `Invalid component.` | Choose a valid **Serial Component** value. |
| `Quantity is required.` | Select a value in **Digits** when the row requires it. |
| `Invalid quantity.` | Select a **Digits** value from the available range. |

**Result:** The applicable configuration area, editing option, or history view is open.

## When the screen does not behave as expected

The list can show its headers while no rows or named controls are available. The configuration
record can also stop at a validation or confirmation message.

| What you see | What to check |
|---|---|
| The list shows **Name** and **Serial Combination** with no rows | Review the list state before choosing a row. |
| No list buttons are visible | The list currently exposes no button control to select. |
| `Component is required.` | Select a component in **Serial Component**. |
| `Invalid component.` | Select a valid component option. |
| `Quantity is required.` | Select **Digits** where the row requires a value. |
| `Invalid quantity.` | Select a valid **Digits** option. |
| `Are you sure you want to delete this row?` | Select **Cancel** to retain the row or **Delete** to remove it. |
| `Serial Combination Changes will be Applied Only on New Jobs, Old Jobs will not be Effected.` | Treat the change as applying to new jobs. |
| `Registration` | Review the audit-log entry type under **Last Modifications**. |
The empty list state included `No data` and the **Tickets** link.

## What to do next

After reviewing the list, continue with the configuration record when you need to inspect or
maintain its component rows.

1. Select the row or its edit affordance in the list.

2. Use [Serial combination details](doc:configuration-serial-combinations-record) for the record
   configuration surface.

3. Use [Reference serial status](doc:configuration-reference-list-reference-serial-status-view)
   for related serial-status reference data.

4. Use [Product serial combinations](doc:configuration-product-combination-view) for product
   serial-combination configuration.

**Result:** You are on the configuration page that matches the next serial-combination task.
