How can I manage one-to-many relationship in Google Looker Studio


I have a Google Sheet which I use as datasource for Looker Studio. The sheet basically is a list of projects and some metrics, with the number of partners for each project. The info could be summarized as follow:

Project ID Partner ID
1 1
1 2
2 1
2 3
Proj ID Budget
1 100k
2 200k
3 500k

Is there a way to represent a one-to-many relationship in google looker?

More specifically I would like to map the location of the Partners on a map chart and the total budget into an indicator. If I use the blend feature, it doesn't show up with correct numbers (for example it sum the project budget for each number of partner). Is there any reference online where I can get more info?

Thanks


Solution

  • I have a work around so you do not have to create a relationship.

    If you just want to be able to select a project on a dropdown and see the budget and the partners ID, I would just link the tables by a combined field name and use a slicer.

    If you have a field with an identical name and data type, Looker should link the 2 together automatically so that if you add a slicer to one it will filter the other table as well.

    If the fields do not automatically join you can create a calculated field in each data table that references the ID you want to use and name the field IDs with exactly the same name. Field names
