We need to understand the business rules, for determine whether entity B is dependent on or independent of A.

When the relationship between two entities is 1 : 1, always A and B are dependent, and you should count 1 LF]]> http://www.functionpointmodeler.com/forum/posts/preList/32/95.page http://www.functionpointmodeler.com/forum/posts/preList/32/95.page GMT
we don't have more information. [b]Customer [/b]has one or more [b]Address[/b].

If you delete a [b]Customer[/b], you also have to delete all its [b]Adresses [/b]..]]> http://www.functionpointmodeler.com/forum/posts/preList/32/96.page http://www.functionpointmodeler.com/forum/posts/preList/32/96.page GMT
Address is entity dependent on Customer. Then, FPA counts the entities Customer and Address as one logical file]]> http://www.functionpointmodeler.com/forum/posts/preList/32/97.page http://www.functionpointmodeler.com/forum/posts/preList/32/97.page GMT
We've got an application to handle Customer Payments. We have an ILF for Customer information (aka probably customer info is split into a few tables, but they together comprise the ILF). We have another table to store customer payments.

Just from that info, would you count the "Payments" table as a separate ILF from "Customer"? I don't know how "Payments" info would be independent of Customers, but do you really have to know more about the [i]use[/i] of the payments information (i.e. look at additional requirements)? The only way "Payments" would be independent is if there is a requirement to report on the Payments info without referencing/including any information from "Customers", right?]]> http://www.functionpointmodeler.com/forum/posts/preList/32/102.page http://www.functionpointmodeler.com/forum/posts/preList/32/102.page GMT
according [b]IFPUG-CPM[/b] are the Payments & Customers [b]1 ILF [/b]to count, if they have instance dependency. It means you have delete all payments of a customer, if the customer has been. deleted.

But if the payment information [i](without customer)[/i] are relevant for the company, you can also delete you customers without deleting theirs payments. In this case you [b]2 ILF [/b][i]Payment & Customer[/i].

Have a nice day
