Plan supports writing back and exporting planning data to multiple destination types, including file-based destinations, data warehouses, and data lake storage. It writes back forecasts, scenario models, and user inputs to backend destinations.
Unlike conventional BI and planning tools that require predefined database schemas and IT-managed writeback infrastructure, Plan supports dynamic database configuration and runtime table creation. Writeback structures are generated automatically based on planning context. Plan also supports semi-structured, on-the-fly writebacks and can write to multiple destinations simultaneously.
This article covers writeback, adding a destination, performing writeback, and logs.
To access writeback options and start writeback, select the Writeback tab.

The Writeback tab includes:
Add one or more destinations to save data using Writeback.

On-premises database servers must be directly reachable from the internet for writeback. They must have a public IP address with port forwarding.
Data writeback capabilities are subject to specific row limits depending on the file source or destination used. While local file formats such as Excel and CSV support a significant volume of up to 200,000 rows, cloud-based integrations via OneDrive and SharePoint are restricted to a much smaller capacity of only 250 rows.

2. In the Create Destination dialog, select + New next to Select a Connection to create a new connection, or choose dropdown to select an existing connection.


Important: This is a one-time setting and cannot be changed later.
After configuring all required fields, select Add to create the destination.
4. After you configure all required fields, select Add to create the destination. The SQL database destination is now configured and ready for writeback.

5. Select Writeback to write your data table. A notification shows the writeback status.

After completion, a confirmation message is displayed.

You can view the written data in the destination database.

6. After the initial writeback, you may add or remove row or column dimensions as you build your report. If the destination structure must change because of these updates, a notification appears. You can drop and recreate the table with the updated structure before the next writeback.

Select View Logs to open the writeback log console. Logs include milestones, payload size, and writeback duration.

Select a writeback ID to view detailed information.
