In this article I will show you how can you link two reports. Passing parameters from one report to another report. Lets start :
I will build a simple report so that it will be easy to understand.
Before creating report the first thing I will do is to create a new formula field on Account object.
Field Name : TempAccountName
Formula : HYPERLINK('https:/Your org/lightning/r/report/your reportID/view?fv0='+Name, Name, '_self')
Note : Group fields by the formula field we have added (TempAccountName ). And fv0 is the parameter. You can add multiple parameters by adding &fv0, &fv1, &fv2 and so on.
Report 1 : Here's my first report "Group Demo" which will list the record count with group by Account name. See below image:
In this report when someone click on Account name it will redirect to another report filtering the records only by Account name.
Report 2 : Detailed report which will show all the detail records by Account Name.
Next step is to add a filter. Go to Filters tab - > Add Filter for Account name as shown in below image and Save the report.
