Authorization issue for Inspection plan & Inspecttion results in one Plant

hi, all, i have an issue about authorization for Insepction plan and Inspection results in one plant..

The detailed scenario is that:

There are 3 business unit in one plant, for example E1 E2 and E3. The Inspection plan and Inspection results are all managed in

one plant . so is there any possibility that the display and change authorization of users for Inspection plan and Inspection

results can be separated from different Business Unit among one plant. They don't hope these inspection plan and results can be

shared by different users in one plant.

Do you have any ideas??/
