Display activity for Tcode FSP0

Dear All,

I need to restrict the access to specific code FSP0 and need to restrict the access for create activity.

Now scenario is that as per functional requirement i had created a role containing t codes" FS00,FSS0,FSP0,FS01,FS02,FS05,FS04,FS06,OB_GLACC11,OB_GLACC12,OB_GLACC13"

now if i tried to make change in authorization object "F_SKA1_KTP" in roles it affects all tcodes in the role and functional people's are not able to preform create activity.

Is their any alternative way to restrict the access to display activity in this role ?

or is there any alternative object to restrict access of FSP0 ??

Regards

Nikhil
