Report workload by calculating how many versions of SharePoint list items created in a certain time period

Question

I have a total of 66 SharePoint 2010 lists - yes, 66! - each lists contains between 1500 and 3200 list items.  My employees update these various list items throughout their workday.  Each update to a list item creates a new version of the list
item.  On average each list item will have anywhere from 5 to 10 versions before it is done.  I need to create a report that tells me how many list items they've updated in a certain time frame.  I have come close but still cannot arrive at
the data I'm looking for. 
This is what I have so far:
I've created a report using SQL Report Builder 2008 v3 where I've filtered it to show only items MODIFIED between, for example, Feb1 and Feb28.  Of those records, I want the report to tell me how many versions were created during that time
frame.  The result is one list item with 5 total versions.  Versions 1.0, 2.0, & 3.0 were created on 12/12/14.  The last two versions, 4.0 and 5.0, were created on 2/24/15.  Therefore, the answer I'm looking for is 2 because they
created 2 versions between Feb1 and Feb28.
However I get the following results using these queries:
If I do a =Sum(Fields!owshiddenversion.Value) in the expression field I get the total versions which is 5
If I do a =Count(Fields!owshiddenversion.Value) in the expression field I get the instance which is 1
Is there a way to count ONLY the number of versions created in a time period?  Is there another hidden field in SharePoint that I can use in the expression that will give me results I'm looking for?

Answer 1

Hi Rafael70,
Per my understanding that you have already get all the need fields and informaiton of the updated version of list items and now you want to calculate how many versions of SharePoint list items created in a certain time period, you can't get desired result
using sum and count function, right?
I have tried to tested on my local environment but because I am not clear what is value in the field "owshiddenversion", I assumed you have two datatype parameters (StartDate and EndDate) to help filter the report in a certain time period.
Generally, if you have add the filter correctly, it will filter the correct number's updated version in this time period, I would like you to provide details information as below to help better analysis the requirements:
Could you please provide sample data of the table.
Please provide snapshot of the report structure you have currently designed.
Please try to provide all the expression you have used.
If you still have any problem, please feel free to ask.
