Global Variant Restrictions
I know that in finance you can control who has access to global variants by an authorization object F_IT_ALV. However, with the rest of the modules (mainly PM, MM) how do you restrict the global variants so they can not be edited? I tried doing an authorization trace on the changing of a variant and no authorization check was done.
I had a similar authorization problem and it was S_ALV_LAYO Authorization object that I used to fix it.
This Authorization object was not found in the authorization trace, so may be you can try restricting the global variants with this object.
