Custom object vs Role transport dependency

Hi Experts,

We built a custom auth object which got  transported to QA before PFCG role but still the PFCG role is not generated via transport. Role is fine in Development.

Can anyone please advise if there is really a dependency between custom auth object and PFCG role ? if yes, which should be transported first ?

PS: Authorization data contains custom auth object in the PFCG role in both Dev and QA except the profile is not generated in QA.

Regards,
