Hi,
To generate a report of variations in the "Qty" and "Total" fields over a date period on a per "EventID" basis, you can use a query in Microsoft Access. Here's an example of how you can create the query:
Open your Access database and navigate to the "Create" tab.
Click on the "Query Design" button to create a new query in Design View.
In the "Show Table" dialog box, select the table that contains your data and click "Add."
Close the "Show Table" dialog box.
In the query designer, add the following fields to the design grid: "EventID," "Qty," "Total," and "ModifiedOn."
In the "Criteria" row of the "ModifiedOn" field, enter the date range you want to filter by, such as:
- Between [Start Date] And [End Date]
- Replace [Start Date] and [End Date] with the actual date criteria, like #01/01/2023# and #12/31/2023#.
In the "Query Type" section of the "Design" tab, select "Group By."
Right-click on the "Qty" field and select "Group By."
Right-click on the "Total" field and select "Group By."
In the "Design" tab, click on the "Run" button to execute the query.
The query results will display the variations in "Qty" and "Total" for each unique "EventID" within the specified date range. You can export the query results to a report for better presentation or further analysis.
I hope this helps!
Best Regards.
