I'm sorry to create confusion.
I'll try to explain it better.
In the publication design I have to specify a list of report to generate, say:
Rep_Result1, Rep_Result2, and so on...
Then i have to define the recipient list using a Crystal Report template, say:
Source_Report
In the Personalization section of the publication I have to define the mapping between Dynamic Recipient fields and the Report field in order to create profiled version of the document for each of the recipient.
Now I'm facing the problem.
My "Source_Report" contains a big amount of records and works fine if I run the publication as is, generating all the artifacts for all of the dynamic recipient in the list; but this is not my target.
I would to define a filter on the "Source_Report" in order to generate the artifacts for a limited subset of the dynamic recipient. Basically I would define a filter on 3 columns of the Source_Report.
I realized that is not allowed to define parameters to apply on the Dinamic Recipient report and then created a copy of the Source_Report with a filter preset on it, but this become unmanageable if I want to cover all the combination of 3 parameters.
If I say that:
Param1 can be set with 3 different values
Param 2 can be set with 5 different values
Param3 can be set with 5 different values
You can easily understand that, with my previous solution, I should preset a total of (3 x 5 x 5) 75 different Source_Report filtered on the single parameter value combination they represent; and obviously change the publication according to it.
I hope to have clarified my question, but available for further info.
