To edit a cost center, click on the "Settings" button at the right top corner of the page. Then a menu will appear with options.
From the menu, click on the "Cost centers" option.
Then the application will redirect you to the "Cost centers" page, where you can see the list of all cost centers. Then you need to click on the "Edit" button from the "Actions" column.
Then a window will appear where you can enter the update cost center name. Once you enter the name, click on the "Update" button to update it.
As an example, let's rename the "Barishal" cost center to "Khulna".
Once you have changed it and clicked on the "Update" button, you will see the updated list of cost centers.
