I have found a workaround that works for me.

Follow these steps to create the report for the entire last month:

1. Go to The Reports http:\\<yourserver>\reports

2. Click on show details on the right

3. Choose one Report you want to schedule and click on the Edit button

4. Click on the Edit Button in the Report definition and save the Report on your drive.

5. Open The Report in the notepad

6. In the first Default Value Section type: DateTime.Today.AddMonths(-1)

7. In the second Default Section type: DateTime.Today.AddDays(-1)

Example:

<DefaultValue>

<Values>

<Value>=DateTime.Today.AddMonths(-1)</Value>

</Values>

</DefaultValue>

<Prompt>Start Date</Prompt>

</ReportParameter>

<ReportParameter Name="EndDate">

<DataType>DateTime</DataType>

<Nullable>true</Nullable>

<DefaultValue>

<Values>

<Value>=DateTime.Today.AddDays(-1)</Value>

</Values>

</DefaultValue>

<Prompt>End Date</Prompt>

8. Save it and go back to the Report tab in your browser click on upload file

9. Click on your Report --> Subscription --> New Subscription

10. Execute your Schedule monthly on calendar day(s): 1

11. In the Start date and End date Values click on both Use Default
