Running report in background job without variant
We developed one report. In that report we have creation date field as select-option in the selection screen. But when we are creating variant there is no option for the default values which are coming from the report.
Ex: Creation date 01.05.2011 to 23.05.2011 (i.e. sy-datum).
We have n number of POs in our production system. So we are taking POs created after May 1st 2011(creation date-low it should be constant) and creation date-high should be sy-datum.
But when I am saving it as varaint, I am not able to get the exact dates in the field.
1. Is it necessary to run a report with varaint in background?
2. If variant is mandatory to run report in background, then how to get creation date-low as 01.05.2011 and date-high as sy-datum.
Kindly help me to sort out the problem facing.
