The SAS© Viya™ Platform File Service allows users to interact with files stored in the SAS© Infrastructure Data Server. Each file is identified by a UUID generated upon its creation. Although a unique name is assigned, it can be modified by the user, which may lead to duplicates. Files are accessed via their file identifier (UUID) found in the URI. The service does not manage 'folders' but allows associating files using the PARENTURI= option, which specifies a relative URI for a SAS© Viya™ platform object, enabling the creation of file collections.
Data Analysis
Type : CREATION_INTERNE
Examples use SASHELP data (sashelp.class) for file creation.

DATA STEP
Explanation :
This example shows how to create a 'class.csv' file from the 'sashelp.class' table using a DATA step. The file is then attached to a specific job using the PARENTURI= option of the FILENAME FILESVC statement. The file service uses this URI to link the output file to the job with identifier '5a308aa7-1c3a-4465-a14c-fd69a9091926'. Each row of 'sashelp.class' is formatted as CSV and written to the 'class.csv' file.

« When utilizing the File Service, prioritize the UUID over the filename for programmatic access. Because the service allows non-unique names, relying on filenames can lead to retrieval errors in automated workflows.
To maintain organization without a traditional folder structure, use the PARENTURI= option to logically group files under a specific object, such as a Job Execution. This ensures your outputs remain contextually linked to their source and are easily retrievable within the SAS Viya ecosystem. »
