You can open the document using the following user_ids
ADMIN ( who can see all 3 sheets)
USER_1 ( who can see all 3 sheets)
USER_2 ( sheet2 is hidden)
USER_3 (sheet2 is hidden)
What i did is I created a REDUCTION field called REDUCTION_FLAG in the section access script and set values as 'NO' for the users who should see all sheets and 'YES' for the users who should not see particular sheet.
And then I mapped that reduction field value ( either 0 or 1) to the REDUCTION_VALUE in section application part.
And I have given the conditional hide for the sheet to be hidden for particular users as follows.
