When I created the paginated report using the published dataset, Its shows me incorrect data as shown below. The paginated report shows that it is making the Cartesian product among these tables.

On further investigation, I found that designer generated the following query.

 

EVALUATE SUMMARIZECOLUMNS('Person'[Id], 'Person'[Name], 'PersonReasons'[TravelReason], 'PersonTravelHistory'[city], "cnt", [cnt])

 

Please let me know how to fix it and shows the correct data as we have in the original table according to the relation.

 

Thanks

What is your reasoning for separating the Travel History and the Reason tables?  Shouldn't they be a single table?

@lbendlin 

this is how I recieve the database, secondly there is no relation in between these tables. it may possible that one of these table have entry and other do not. the important there here is both are child of person table.

You can have a Reason entry without a corresponding Travel entry?

there can be travel entry without reason entry.

combine the tables and accept that the reason field may be empty

would you please provide the complete steps or better to provide the pibx file and rdl files for better understanding?

 

thanks
