Access: finding the corresponding value of maximum value - ms-access

Question

I have a database in which I perform an audit on a set of required documents, for several locations of those documents.
So I have a table named Locations and a table named Documents, which are correlated through a 2 x 2 relationship.
Every document can have multiple versions. In my query, I want to see only the most recent version of each document, so the max(Id).
Now, every version can be 'audited' (checked) multiple times, for example 2 times each year. Each Audit/check is stored in a record, and I want to show only the most recent audit for each document, so Max(ID).
This is my Selection Query:
SELECT [~Locations].Location, [+DocuProperties].Category, [~Documents].[Document name], Max([DocuVersion].Id) AS MaxDocuID, Max([Audit].Id) AS MaxAuditID, [Audit].Conclusion
FROM ([~Documents] INNER JOIN ([~Locations] INNER JOIN ([+DocuLocation] INNER JOIN [+DocuProperties] ON [+DocuLocation].Id = [+DocuProperties].DocuLocation) ON [~Locations].Id = [+DocuLocation].Location) ON [~Locations].Id = [+DocuLocation].DocuName) INNER JOIN (DocuVersion INNER JOIN 2Audit ON [DocuVersion].Id = [Audit].DocuVersion) ON [+DocuProperties].Id = [DocuVersion].DocuLocation
GROUP BY [~Locations].Location, [+Docuproperties].Category, [~Documents].[Document name], [Audit].Conclusion
However: I do not wish to Group on Audit Conclusion, I wish to show the Audit conclusion that corresponds to the Max(Id) of that Audit.
So for every most recent Audit, I want to show the Conclusion. This conclusion I want to show for each Document, grouped byCategory and grouped byLocation.
I know I need to build a nested subquery of some form, but I just can't get any code to work.
I hope anybody can help.

Answer 1

The basic idea is like this:
Table 1
DocuProperties
Id Location Category
1 15 1
2 15 1
3 14 2
(every location can have multiple document properties a.k.a. objects)
Table2
DocuVersion
Id DocuProperty DocumentEndDate
1 1 01-01-2022
2 1 20-07-2023
3 2 31-07-2023 etc.
4 3 01-10-2023
(every DocuProperties can have multiple versions, I have to check If they are still valid, but also on some other criteria ).
Table 3
Audit
Id DocuVersion Conclusion
1 1 Not Valid
2 1 Not Valid
3 2 Valid
4 4 Valid
(every version can be audited multiple times. Every audit can have a different conclusion)
Which I would like to translate into the following:
LASTAudit (a.k.a. the most recent audit of the most recent version of the most recent property)
Location DocutPropertyId DocuVersionId AuditId Conclusion
15 2 2 2 Not Valid
14 3 4 4 Valid
The ID’s were easy to get right, as those were just Max(Id) functions. The problem was to get the Conclusion corresponding to that audit of that version of that object.
