ABAP Query Variant Does Not Exist

Hi,

After remote client copy from production to quality server with copy profile “SAP_ALL”, I faced with “Variant does not exist” for ABAP Query.

TCode SQ01, execute query with Variant, the pop up did show the variant, but when continue, it just show “Variant xxx does not exist”. 

I checked in production, the variant was not protected.

May I know how to solve this?

Thank you.
