Other than the existing Cloudbeds Data Fields (CDFs), you can also create a new custom CDF to generate unique calculations or to create new descriptive fields to your report.
Notes:
- It's not possible to join CDFs from different report types.
- You can create custom CDFs when customizing Cloudbeds Reports or editing a Saved Report.
Create a new custom CDF
- Inside the report, click Custom CDF.
- The option Custom CDF can also be found in the Columns section by clicking ADD+.
