# How to reset document numbering at year-end?

Before starting sales in the new fiscal year, make sure that document numbering is set up correctly. The cairo.ERP system automatically resets document numbering and also updates year symbols (e.g., **yyyy** or **yy**) and month symbols (**mm**) if they are used in the numbering format.

Regardless of the automatic settings, before you begin working in the new year, it is worth checking the following elements:

- Document numbering and number extensions
- Cash document numbering
- Numbering of RW (internal release) and K+ (stock correction) documents

### **Resetting numbering for all documents (for the highlighted warehouse)**

If necessary, you can manually reset document numbering or change number extensions, such as the year or month.

1. Go to **ERP > Administration > Warehouse List**.
2. Highlight the warehouse you want to edit, then press the **\[Insert\]** key to enter the numbering and extension overview for that warehouse.
3. To reset the numbering, press the **\[F2\]** key.
4. If the year was entered manually in the number extension (e.g., **2025**), change it to the current year (e.g., **2026**). You can also use templates that the system updates automatically, such as:
    
    
    - **<yyyy>** (current year in four-digit format, e.g., **2026**)
    - **<yy>** (current year in two-digit format, e.g., **26**)
    - **<mm>** (current month, e.g., **08**)
    - **<mag>** (warehouse symbol, e.g., **CE**) You can also create your own combinations of templates, for example **/<mag>/<yyyy>**.

This procedure must be repeated for each warehouse. To change the warehouse, press the **\[F5\]** key.

### **Checking cash document numbering**

You must check and, if necessary, edit cash document numbering in the cash register settings.

1. Go to **ERP > Administration > Parameters > Cash/Bank > Cash register list**.
2. Press the **\[Enter\]** key on the selected cash register.
3. Check and change the **KP NUMBER**, **KW NUMBER**, and **EXTENSION** parameters.

### **Checking RW and K+ document numbering**

If the numbering of internal release (**RW**) and stock correction (**K+**) documents is based on groups, you must verify it in the document group dictionaries.

1. Go to **ERP > Administration > Dictionaries > K+ stock correction document groups**.
2. For each defined **K+** document group, press **\[Enter\]** and change the **LAST NUMBER** parameter setting.
3. Perform the same procedure for **RW** documents by going to **ERP > Administration > Dictionaries > RW document groups**.

After completing these steps, the numbering will be reset according to the selected method.
