Visibility Permissions - Thingworx

Hi all,

I am having a doubt on visibility and run time permissions for things.

My scenario is:

1. Thing Template

     a. Thing 1 (Unit 1)

     b. Thing 2 (Unit 1)

     c. Thing 3 (Unit 2)

Organization  ----> a. Unit 1 ----> User 1

                               b. Unit 2 ---> User 2

I gave visibility permission as per mentioned above. In main template, for "getImplementedThingsWithData" service enabled all permissions for all users.

In mashup, i created a drop down list by using "getImplementedThingsWithData" as data source. But am able to see all the things in that drop down list.

I want see limited things as per the scenario.

how to resolve this workflow?

Thanks & Regards,
