List items cannot have alternative items, because then the specific component of the list that is replaced is not clear. You can specify alternative items for items of the following types:
- Purchased
- Manufactured
- Generic
You cannot define alternative items for standard-to-order items.
Segmented items consist of a project-code segment and an item-base segment (the item code). Segmented item codes are defined in the Item Code Segmentation (tcibd0500m000) session.
