There are two ways of changing the reversal or credit document series:

- In the document file, in **[Marketing & Sales / Procurement] | [Sales / Purchases] | Resources | Tables | [Sales Document / Purchase Document]**;
- In **Other Utilities** of the Administrator.

Considering that usually, at the end of the year, new series are created, changing the reversal or credit document series would be a difficult task. In order to facilitate changing the series in several documents simultaneously, we suggest using the option **Other Utilities**..

To correct the reversal/credit document series, follow these steps:

1. Access **Administrator | [Company] | Business Application Foundation | Other Utilities**;
2. On the tab **Reversal/Credit**, the original Sales, Purchases and Internal documents are presented with the associated reversals/credits;
3. Select the original document; **Note**: Several documents can be selected;
4. Change the series. Only the series that correspond to the selected reversal document can be chosen
5. Click **Confirm**.

> [!NOTE]
> If the selected reversal document has the same nature as the original document, the options **Allows negative rows** and **Allows negative document** in the original document must be active.
