Query Code Extension Logs by Using Query Editor (Beta)

Use Query Editor in Data 360 to view logs generated for custom code runs. Logs are stored in the Data Lake Object (DLO) named DataCustomCodeLogs__dll, and you can query them like any other DLO.

Code extension is a pilot or beta service that is subject to the Beta Services Terms at Agreements - Salesforce.com or a written Unified Beta Agreement if executed by Customer, and applicable terms in the Product Terms Directory. Use of this pilot or beta service is at the Customer's sole discretion.

You can also use Data Explorer to view custom code logs saved in the DLO named DataCustomCodeLogs__dll. See View Your Data in Data Explorer.
