How to reuse ID generated in one test case to another

Hello Team,

I am working on a application where users with different roles and access rights are involved. The base level user submit a report which has to be approved by other users( user at higher level in hierarchy). Each time a report is submitted, a submission ID is generated which is used for futher correspondence. I have created two fully functional test cases which are: 

Test 1: Create abd submit new report

Test 2: Approve Submitted report

I am planning to integrate both the test cases so that whatever submission ID is generated by first test case, can be populated to the 2nd test case. Right now, I am explicitly entering the ID in 2nd case to filter out the report to be approved. Through forums and internet, I got a rough idea that some data binding and coded step is involved but could not figure out the correct solution.Can someone help to achieve this goal?

Thanks
