Parental Lookup OIM

Hi Everyone,

I am stuck in situation, please read below case:

Lookup.User.Company

A

B

C

D

Lookup.User.Office

1

2

3

4

Lookup.User.Location

P

Q

R

S

T

U

V

Now I want to select Location in UI based upon Company and Office:

Like Map:

A 1 -> P

A 2-> Q

B 1-> R

It means If Company is A and Office is 1 than P should come, like that

Anyone can help how I can achieve this in OIM
