ReadyAPI Functional Testing Automate Problem

I am writing the test suite for my endpoints.I am having one problem which is for running the 1 test suite twice. For Example, When I add an image with endpoints it adds the Image with a unique Id and returns successfully. This unique Id is generated new every time. So we have another endpoint where we pass unique IDs to delete. So it is successful for the first time but when we run the delete second time the same query then that id is deleted and it says it does not exists. how do we automate this thing? I mean the test case should not fail.

I tried to search but could not able to find any resource, Any help will be appreciated. Thanks.
