Business Context
An operations team has developed a standard set of utility actions (e.g., for custom logging, data quality checks) and saved it. A new analyst in a different CAS session needs to load this toolkit to perform routine data validation on a new dataset.
Data Preparation
First, define a custom action set 'opsToolkit' with a 'checkNulls' action. Then, save this action set to a CAS table named 'toolkit_table' in the 'CASUSER' caslib for persistence.

| 15 | print("Check complete."); |

| 25 | RUN; |
| 26 | QUIT; |
Étapes de réalisation
1
In a new session, restore the 'opsToolkit' action set from the persisted table 'toolkit_table'.
Copied!
| 1 | PROC CAS; |
| 2 | BUILTINS.actionSetFromTable / |
| 3 | TABLE={name='toolkit_table', caslib='CASUSER'}; |
| 4 | RUN; |
2
Verify that the 'opsToolkit' action set has been successfully loaded into the current session by checking its information.
Copied!
| 1 | PROC CAS; |
| 2 | BUILTINS.actionSetInfo / actionSet='opsToolkit'; |
| 3 | RUN; |
| 4 | QUIT; |
Expected Result
The 'opsToolkit' action set is successfully restored and becomes active in the new CAS session. The output of `actionSetInfo` should display the details of the 'opsToolkit', including its 'checkNulls' action, confirming it is ready for use.
