BPC Member Access Profile

As the description in the user guide, we could find that if there are 2

different Member Access Profile, the least restrictive profile between

the two, will be applied.

Here is our question:

Access Authorization Entity Account

Profile A "Read/Write" "Human Resource" "All of the accounts"

Profile B "Read/Write" "All of the entities" "1000-Salary"

We set an ahthorization with 2 different dimensions. If we assign the

both Profile A and Profile B to the user in HR department, what we

expected is he can write in all of the account in his own entity and

write in account 1000-salary for all of the entities in company, but in

fact he got the authorization to Read/Write all of account in all of

the entity.

Apparently it's not the result we expected.

Does anybody have any good idea on it?
