batch job- crystal report

SUGGESTED

hi,

How can I have a crystal report batch job automatically default the parameters to the current date?   As is now we have to manually change the task management every date to change the date range but we would like for the report to run automatically with the current date.  would I have to change the crystal report to point to 'currendate' parameter? 

would the job run then for each day?

the report is a daily sales report that we want to send via email for each days sales order entries.

hope i'm explaining this clear.

any help is appreciated! thanks

Christine
