Trelica can import spend data from BigQuery. Configuration will require sufficient administrative rights in Google Cloud Platform (GCP). 

The first step involves creating a view in BigQuery. We have a recommended view structure but Trelica can also support custom views.

Once a view is created you will need to create a billing project and service account.

This account is then granted permissions on a view in the BigQuery dataset that you wish to share.

Create a BigQuery view

We recommend you create a view on your spend data with a standard structure which Trelica can process without additional work. If this is not possible, then you can open a request with for manual view configuration.

The view should be called trelica_spend

  3. Click Create service account:
  4. Enter a Service account name: as you type a unique servive account ID will be automatically generated.
  5. Note the generated Email address (you will need to provide this when connecting Trelica to BigQuery - a copy will be in the JSON key file you will shortly download).
  6. Click Create and Continue.
  7. Assign the BigQuery Job User role by either searchign or selecting in one of the Quick access lists if available.

  15. Once you have entered these details into Trelica you should delete the file (i.e. also remove from any trash or recycle bin).
  16. You can regenerate the key and re-enter it into Trelica at any time if you need to.
