Test Case document Not coming in Test Plan Generation

Hi,

I am using Solution Manager 7.1 SP 12 (for BASIS and ABAP).

I have created a project structure and assigned the transactions and Test Cases in SOLAR02 transaction. I am able to view the test Case documents in solar02 t-code. I have maintained the status of Test Case documents as Released.

Now when i am trying to create the Test plan in transaction STWB_2, with released test documents only,  the test documents are not coming for selection, only the tcode are available for selection during generation of Test Plan.

Can anyone please advice why these test case documents are not coming fr selection in STWB_2 transaction.

Do i need to to anything apart from saving the tet doc in release status or it needs some kind of authorization or configuration so that Test cases are available for selection during generation of Test plan.

Thanks in advance.

Regards,

Nidhi
