Parameters doesn't autogenerate prompts

[soms123]

Hi,

I am using paramters in my report. In my report i have query1,query2,query3. I use filters using startdate and enddate in query 2 and query3. But it doesn't autogenerate the prompts. There is a master detail relationship from Query1 to query2, 3 and 4. If i use the parameters in query1 it will autogenerate. But i don't want that filter in query1. How do i achieve this?

I can't use prompt page. Need to autogenerate the prompts. Please help!
