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.
