Master-detail Cognos report with parameter

Question

I need to create a report using two data sources in cognos 10. A master source has a "column" named id which i want to use as second data source parameter. I create a master detail relationship from id to my parameter, but to all details id from first row is passed.

How to change it to a situation where id from row is passed?

A detail(x) is a effect of second data source with passed parameter.

Answer 1

You should be using two different queries and two different list objects. The detail list should be nested inside the parent list. They should then be linked via the Master-Detail Relationships property. Double-check the join, as many developers are prone to misclicks on this screen.

Here is a good walkthrough on creating what I described above.
