lpd_cust role MSS Instance SUB_UI5 Not visible/missing in one client

Hi

We are not able to see the role: MSS, Instance: SUB_UI5 in a client say 300. But whereas its available in client 200.

So when I try to create "Read from other system using RFC" it says SAP_UI5 instance version 0001 already exists.

I have the same pfcg roles and profiles in both the client.

- Do you know why its missing in one client and visible in another client (though we have the required business function activated in client 000)

- How do we get back the SUB_UI5 and other missing roles in our lpd_cust?

Thanks

Senthil
