Delegated user admin and export Roles&Groups ?

Hi experts,

I'am searching some tips in order to allow my users's delegated user admin group to export UME Roles and Group. however, my users met no problem to assign their roles to themselves

I'am working on EP 7.0 sp14 and my UME is an abap system

Can you give me some advice to go out from this issue ?

Best regards,
