RFC does not approved without CD

Hi ChaRM Expert,

We are using Solution Manager 7.1 SP 10.

RFC is stuck due to no Document type in Scope assignment block and the status is "Approved".

So,I just want to know where we can do the restriction like no one can approved the RFC without Document type.

Please suggest me the standard process or is it any bug.

See the screenshot.

Regards,
