If you want to create an item, there are several ways you can do this.
If you want to create a new item, you can either click on the round button in the main window or right-click in one of the item lists and then click on “Create a new item”.
If, on the other hand, you want to create a similar item so that you do not have to enter all the data again, select any item, right-click and click on “Sell similar item”.
Then the item management window will open, which will be described in the next chapter.
