You create a new where-used list for an address or person in the following cases:
The Where-Used List During Address/Person Number Assignment
You pass the structure of the where-used list using a parameter of function module <object>_NUMBER_GET (see Working with BAS). In the default setting, BAS automatically set the owner indicator (parameter OWNER ) when the number is assigned even if the structure passed specifies something different. If the address should not have an owner, you must set function module parameter OWNER to SPACE .
Whether an address has an owner or not is important when it comes to deleting the where-used lists and the address or person itself (see
Creating Additional Where-Used Lists
In order to create additional where-used lists, you use function module <object>_REFERENCE_INSERT . You must delete these where-used lists first before you can delete an address.
