How to display record selection settings in the result

Question

Hi,
CR 2008 and 2013 are being used, but this is a rather general question.
We are generating different schedules using one source file. Depending on the filter setting on the data scope, say CURRRENTDATE or last month, daily or monthly reports are sent out.
The problem is, when there is no data included in the report, we would like to put a message in the report saying "There is no data found in the period xyz". But so far we haven't figured out how to retrieve the different filter settings in the schedules.
Is there a way to do this? I do hope we don't have to create different .rpt files just for different schedules.
Any suggestions and opinions are appreciated.

Answer 1

While, the reports can be run manually by the user with a prompt asking the range or scheduled on the server and sent out automatically without interaction.
For the latter case, the prompt for date range was written as optional. And the record selection looks like this:
IF (HASVALUE({?dFrom}) AND  HASVALUE({?dTo}))
THEN
{a_table.dDate}>={?dFrom}) AND {a_table.dDate}<={?dTo}
With the user input, everything is ok. But while scheduling a report on the server, we set the prompt to EMPTY and control the range by using a filter. For a daily report, the record selection changes to
{a_table.dDate}= CURRENTDATE-2
Here comes the problem. Without being able to read this value into the report, we don't know how to show period xyz in an empty report, because a daily report could also query CURRENTDATE or CURRENTDATE-10, depending on the schedule. The same applies to monthly reports. People can schedule a report to run once a month, but still query just CURRENTDATE by mistake.
So the most reliable information is to read out what is set in the filter...
