Use
Sub-items are used to describe the different installation points of these partial quantities.
Prerequisites
In Customizing for Bills of material (work step Item data → Define item categories), you can define whether sub-items are supported for each individual item category. In the standard system, for example, sub-items are supported for the following item categories: Stock item Non-stock item Variable-size item PM structure element
Procedure
You can start the function for entering sub-items either from an item overview or from an item detail screen.

If you are on an item detail screen, start with step 2.

Subitem.
You see the Subitems screen, on which sub-item numbers are already given.
- Enter the subitems.
You can enter the following data:
– Installation points

The system compares the item quantity to the sum of all sub-item quantities. If the item quantity is different from the sum of the sub-item quantities, the system changes the item quantity.
You see the following information:

– Sub-item description
Enter a descriptive text for the sub-item (up to 40 characters).

Result
On the item overview, all the items that have sub-items have the Sub-items exist (SIs) indicator.
Once you have entered sub-items for an item, you can only change the component quantity on the sub-item overview.
