Creating Where-Used Lists
You create a new where-used list for an address or person in the following cases:
You assign a new address or person number
You save a new reference to an existing address or person, for example, if you add a workplace address for an existing person or enter a document that refers to an address.
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.
Note
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 Deleting Where-Used Lists and Addresses).
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.
