## How to Configure the Default Document Prefix in Packing Slip–Delivery Orders?
In this tutorial, we will learn how to define a **Default Document Prefix** for Packing Slip entries in Logic ERP. This feature allows users to configure multiple document prefixes and select the required prefix while creating a Packing Slip.
***
### Objective of This Feature
* Define a default document prefix
* Configure multiple document prefixes
* Select the required prefix during Packing Slip entry
* Maintain organized document numbering
* Simplify document identification and tracking
***
### Observe the Default Behavior
By default, the system automatically displays the **DO** document prefix in the Packing Slip Number field.
* Default Document Prefix: **PS**
* The system automatically uses this prefix while generating a new Packing Slip.
***
### Configure the Document Prefix
* Open the **Configuration Window**.
* Navigate to the **Other Options 1** section.
* Locate the option labeled as:
> **"Default Doc Prefix"**
* Enter the required document prefix.
* To define multiple prefixes, enter them **separated by commas**.
**Example**
* You can define multiple prefixes such as:
* **PS, DO & PSD**
* Save the configuration changes.
***
### Create a New Packing Slip
* Initiate a **New Packing Slip Entry**.
* Check the **Document Prefix** field.
**Result**
* The **Document Prefix** field now displays a **dropdown list** containing the configured prefixes.
* You can select the required prefix while creating the Packing Slip.
***
### Key Benefits
* **Flexible Numbering:** Define multiple document prefixes as required.
* **Easy Selection:** Select the appropriate prefix directly during entry.
* **Better Organization:** Helps categorize and identify Packing Slips.
* **Reduced Manual Effort:** Configured prefixes are readily available.
* **Improved Document Tracking:** Makes document numbering more structured.
***
### Final Outcome
After configuring the **Default Document Prefix**, Logic ERP provides a dropdown list of the defined prefixes during Packing Slip entry, allowing users to select the appropriate prefix and maintain organized document numbering.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/billing/packing-slip/packing-slip-configuration/default-doc-prefix.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
