Business Context
A marketing department needs to structure its data for a new campaign. They require a dedicated, secure subdirectory within their main caslib to store customer lists, creative assets, and performance results. Access needs to be controlled for collaboration and compliance.
Data Preparation
Initial setup of the primary marketing caslib. This ensures a valid target location exists before attempting to add a subdirectory. The path '/cas/data/mktg' is assumed to exist on the CAS server.

Étapes de réalisation
1
Create a new subdirectory for the 'Winter_Promo_2025' campaign with specific group permissions to allow the marketing team to read and write, while other departments can only read.
Copied!
| 1 | PROC CAS; |
| 2 | TABLE.addCaslibSubdir / |
| 3 | caslib='mktgData', |
| 4 | path='Winter_Promo_2025', |
| 5 | permission='GROUPWRITEPUBLICREAD'; |
| 6 | RUN; |
2
Create a nested subdirectory to store campaign results. This tests the ability to create directories within a newly created subdirectory.

| 1 | PROC CAS; |
| 2 | TABLE.addCaslibSubdir / |
| 3 | caslib='mktgData', |
| 4 | path='Winter_Promo_2025/results'; |
| 5 | RUN; |
3
Verify the creation and permissions of the new directories using the fileInfo action. This confirms the successful execution of the previous steps.
Copied!
| 1 | |
| 2 | PROC CAS; |
| 3 | TABLE.fileInfo / caslib='mktgData' path='Winter_Promo_2025/'; |
| 4 | RUN; |
| 5 |
Expected Result
The action successfully creates the 'Winter_Promo_2025' directory and its nested 'results' subdirectory inside the '/cas/data/mktg' path. The `fileInfo` action output will list the 'results' directory, and the 'Winter_Promo_2025' directory itself will have file system permissions equivalent to 775 (rwxrwxr-x), confirming the 'GROUPWRITEPUBLICREAD' setting was applied correctly.
