Good question.

This is what it does

• A group can have a customer number
• A user can be member of one or more groups
• If a price has group customer number on it, the current user will get the price if they are member of that group
• If a user is member of 2 or more groups, where more of them have a group specific price, the lowest will be used.
• If a user have a customer or user specific price also, all prices come into consideration and the lowest will be used.

Use case

• You can use it for price groups
  • Users might have a customer number on them selfes - that can give them user or customer specific prices
  • But users can also instead be in a more generic group - i.e a price group and get price group specific prices

In user management, consider this group structure.

• Accounts
  • Company A (User 1, User 2) - All users share the same customer number, maybe also the group have that customer number.
  • Company B (User 3, User 4) - All users share the same customer number, maybe also the group have that customer number.
• Price groups
  • Price group 1 (User 1, User 2, User 3, User 4)
  • Price group 2 (Other users)

Since you can just use the group field instead, that would be the same - difference is that this might be easier to integrate since group customer number can hold any ID - where as the group field needs the group id.

This is the code:

private static bool CheckUserGroupCustomerNumbers(Price price, User user)
        {
            if (!string.IsNullOrWhiteSpace(price.CustomerGroupId))
            {
                if (user is null)
                {
                    return false;
                }

                foreach (var g in user.Groups)
                {
                    if (string.Equals(price.CustomerGroupId, g.CustomerNumber, StringComparison.OrdinalIgnoreCase))
                    {
                        return true;
                    }
                }

                return false;
            }

            return true;
        }
