Sample tab in inspection plan and result recording to be suppressed

Dear QM Gurus ,

Our client will not be using physical sampling and hence in the sample tab ,apart from the sampling procedure the other fields sampling UOM and the sample size is inconsequential for the users in inspection plan and result recording .

So as to prevent the users from entering incorrect data in these two fields in sample tab , our users want the two fields to grey out and prevent any user entry ..How ever the sampling procedure entry should be made in inspection plan .

Kindly suggest the config and master settings by which all the fields except sampling procedure can be suppressed or greyed out , unavailable for input or change ..

Helpful answer will be rewarded appropriate points immediately
