Concurrent Request for a specific request group appearing on other submit request

Hi.

I have create a new responsibility with the application Payables, and i have created a new request group for it with the application Payables. but when i run the concurrent request from the other responsibility under the same application payable, i found the list of values for the new request group there.

I want to know how will i be able to prevent or restrict the other responsibility to view the request program for the specific request group create.

i want only my new responsibility to be able to view the new request group's program.
