CDA - caching query for different parameters

Hi Pentaho-guys,

I was checking how to schedule caching query with CDA. I found the possibility in CDA, where you can next to preview, cache your query. My problem is that query should run for different parameters, better said combination of parameter.

My queries are:
get_period - Day, Week, Month
get_date_from, get_date_to - using by user selected Period go to mapping table and find values
get_data - with dates mentioned above get number of XY

How can I schedule this on daily basis - I found $FOREACH(get_date_from, dateFrom, param1=val1,...,paramn=valn), but I don't know how to fulfill val1 ... valn.

I would be really happy to hear from you how you are dealing with such cases.

Best regards,
