Restriction Group by VENDOR

I’d check out Usage Example 2 in the link here: https://help.acumatica.com/(W(5))/Help?ScreenId=ShowWiki&pageid=a72c11e3-e181-4412-a462-ce333721a1e9

Items that are not in any groups are visible to all users, so the other vendors also need to be added to groups as well.
 

Problem statement: Suppose that as a system administrator, you have to configure the visibility of accounts to the appropriate users considering the following:

• There are four accountants: User C, User D, User Y, and User Z.
• There are six accounts in the General Ledger module: Account 1, Account 2, Account 3, Account 4, Account 5, and Account 6.
• User Y works with only one sensitive account, Account 1; User Y is not allowed to see the following accounts: Account 2, Account 3, Account 4, Account 5, and Account 6.
• The other accountants work with all accounts except Account 1.
• Only accountants have access to the Finance suite. (Thus, there is no need to hide accounts from other system users.)

Solution: To address the problem of Usage Example 2, you can create two restriction groups—Group 1 of type A or B, and Group 2 of type A Inverse or B Inverse. (If you select type A for Group 1, you should select type A Inverse for Group 2. If you select type B for Group 1, you should select type B Inverse for Group 2.) These groups are defined as follows:

• Group 1: In this group, you include User Y and Account 1. (Other users will not see Account 1.)
• Group 2: In this group, you include User Y and Accounts 2 to 6. (User Y will not see these accounts.)

The following diagram illustrates the proposed solution.

THANK YOU! That is close, but then everyone else would lose visibility right? Or do I just say that all my OTHER users are in BOTH groups? Everyone at my company should see EVERYTHING, except for ONE user who should see ONE VENDOR ONLY. I saw that article you linked and it didn’t quite cover my case as it shows everyone only seeing PART of the system. I need all my users (except one) to see everything and that one user to only see the single vendor.
