**Partition Required:** If the Inforiver scenario is created and included in the writeback, and the user wants to writeback base and scenarios in separate parquet files, this is recommended.&#x20;

**Insert Variables:** Writeback file name can be customized using variables such as Execution ID and date time related IDs.

**Security:** Please note Inforiver leverages Azure Access Control Lists (ACLs) while configuring Azure Data Lake Storage as a writeback destination. That means the user is only shown folders and directories that they have access to as per the defined ACL rules.

### Roles

Ensure that the user has the permissions listed below.

In Inforiver managed mode:

1. Read on the storage account
2. Read and Execute on the file system
