Hi Antonio,
Are you reffering to restrict the columns mentioned only for a specific Plant?
Im not sure if you can do it with a SHD0, maybe, if you cannot do it, the best way can to be create a non-standard transactions or add in a user-exit, etc. of the standar program any restriction about the specific Plant.
Sorry for it, I hope that any developer can resolve the doubt.
Please let us know with anything.
Best regards.
