Assuming ReportNet....
In the tabular model of your crosstab (parent) query, include a query item for each prompt value, and set the value of the data item to the parameter. Then in your list (Child) report, include three optional filters using three new parameters (one for each of the prompts in the parent report). Then in the drill through, link the query items from the parent report to the parameters in the optional filters in the child report.
Example:
If you have in the crosstab report the following prompts:
* Start Date (parameter = parm_StartDate)
* End Date (parameter = parm_EndDate)
* Location (parameter = parm_Location)
In the parent crosstab report query, create three data items in the tabular model:
* Data Item Name = StartDate
Data Item Derivation = ?parm_StartDate?
* Data Item Name = EndDate
Data Item Derivation = ?parm_EndDate?
* Data Item Name = Location
Data Item Derivation = ?parm_Location?
In the child list report query, create three optional filters:
* [StartDateColumn] >= ?parm_StartDate?
* [EndDateColumn] <= ?parm_EndDate?
* [LocationColumn] in ?parm_Location?
Finally, go back to the parent report, edit the drill through, and the three new parameters from the child report should be added. Set them as follows:
* ?parm_StartDate?=StartDate
* ?parm_EndDate?=EndDate
* ?parm_Location?=Location
Thats it!
