**SQL Code Description**
==========================

### Purpose

This SQL code retrieves the part number and maximum revision values for each unique product in a database table.

### Components

*   **Table**: `[Util Make Duplicate Revision Remover 1]`
*   **Columns**:

    *   `prt`: Product identifier
    *   `Rev`: Revision number
    *   `PN`: Part number (alias)
*   **Subquery**:

    *   `[Util Make Duplicate Revision Remover 1].Rev` and `[Util Make Duplicate Revision Remover 1].PartNumber`
        +   These subqueries extract the revision numbers and part numbers from the original table.
*   **Aggregate Function**: `Max()`

### SQL Code Breakdown

#### Select Clause
```sql
SELECT 
    [Util Make Duplicate Revision Remover 1].prt, 
    Max([Util Make Duplicate Revision Remover 1].Rev) AS Rev, 
    Max([Util Make Duplicate Revision Remover 1].PartNumber) AS PN
```

*   The code selects three columns:
    *   `prt`: Product identifier
    *   `Max([Util Make Duplicate Revision Remover 1].Rev)`: Maximum revision number for each product (using the `MAX()` aggregate function)
        +   The subquery `[Util Make Duplicate Revision Remover 1].Rev` extracts the revision numbers.
        +   The `MAX()` function returns the maximum value from this subquery.
    *   `Max([Util Make Duplicate Revision Remover 1].PartNumber)`: Maximum part number for each product (using the `MAX()` aggregate function)
        +   The subquery `[Util Make Duplicate Revision Remover 1].PartNumber` extracts the part numbers.

#### Grouping Clause
```sql
FROM [Util Make Duplicate Revision Remover 1]
GROUP BY [Util Make Duplicate Revision Remover 1].prt
```

*   The code groups the results by `prt`, which means that each group will contain one row for each unique product identifier.

#### Sorting Clause
```sql
ORDER BY [Util Make Duplicate Revision Remover 1].prt, Max([Util Make Duplicate Revision Remover 1].Rev) DESC;
```

*   The results are sorted in descending order by `Max([Util Make Duplicate Revision Remover 1].Rev)` within each group.
*   Within each group, the results are also sorted by `prt` in ascending order.

### Example Use Case

This SQL code can be used to:

*   Determine which products have the highest revision numbers and their corresponding part numbers.
*   Identify any inconsistencies or discrepancies in the data by comparing the maximum revision number and part number for each product.
