PFCG S_RFC not modifiable

Dear all,

After upgrade 4.7 to ECC, I am now in version :

SAPKB74009 SAP Basis Component

SAPKA74009 Cross-Application Component

When I create a role with transaction and S_RFC object linked to the transaction : I cannot modify the objet S_RFC.

Same thing for S_SERVICE object.

I saw following notes : 745655, 612585, 624207... but it's not for my version.

Somebody can help me please ?

Thanks and regards,

Mélanie
