To enter a material item:
Once you have entered and confirmed an item, you can no longer change the item category for the component. If you enter an incorrect item category, delete the item, and then enter it again with the correct item category.
The new item is not created until you have entered all the required data for the item. The required data is different for each item category. For example, for a variable-size item you must enter sizes, and for a non-stock item you must enter a material group.
If the system recognizes that an entry is missing or incorrect, it displays the corresponding item detail screen. You can add the missing entries or correct the incorrect entries on this screen.
