@fixedtermzaidhabeeb you'll need to do this with a flow in Power Automate. The trigger would be when an item is created or modified, Then add an initialize variable action (integer) with the current value, then add an increment variable action and set the increment to 1. Then you can use an update item action to save that increment value to the item in the SharePoint list.
