drill through cognos date range Cognos 10

[andregomes]

Good morning people,

I'm having a problem drilling through using a date range.
I'll explain what I want to do with the report:

I have a bar chart where I have the amount, time interval in the format (YYYYMMDD HHMM) and the report runs on my server. Opening this report prompts you for a range prompt ('start day / time' and 'end day / time') to show the data. When you click on the chart you need to open the child report with the details of that selected time. At the moment I'm passing by parameter in drill the data item value of "Interval" and I make the comparison in the child report with the same field in the prompt filter. The value is passed but the report does not execute. What is the best way to make the child report show me the date and time I clicked on the drill? What kind of data should be compared in the filter?

Thank you all.
