Crystal Reports - is this possible?

[rich_g85]

Hi all,
I've got a very simple Crystal Report which calls a Sybase stored procedure.

The SP requires one parameter: @for_date

I want the report to run daily, for YESTERDAY's date.

How do I tell Crystal to do that?
eg: exec coredb..usp_ext_r_log_exception @for_date = {YESTERDAY}
