SAS Information Catalog
The new StepInputColumn and StepOutputColumn search facets enable you to search for SAS Studio data flows by the input and output columns in the flow steps.
SAS Studio
Impact analysis helps you identify the potential consequences of making a change to a table or column. You can run an impact analysis on a table and then select columns from the table to analyze as well.
SAS Job Execution
Compute Tasks is a method of executing a task that prioritizes speed over resilience. The method is used to create a session, submit the program, wait for the program to finish and retrieve the output in a single HTTP request.
Use Case
SAS Studio - Impact Analysis
Confidently manage and modify your data assets without the fear of unintended consequences using the new impact analysis feature. This powerful tool acts as your data lineage and dependency map, allowing you to instantly assess the ripple effect of any proposed change.
With forward impact analysis, you can proactively identify every downstream report, flow and data asset that depends on a specific table or column before you make a critical update. Conversely, reverse impact analysis provides a complete upstream lineage, tracing exactly where your data originates from, which is essential for debugging, validation and governance.
Tip of the Month
Brought to you by David Weik

Quick tip: How to see what’s in a CAS library.
Ever loaded data into a CAS library (CASLIB) and wanted a quick, clean summary of what’s currently in memory? Instead of hunting through logs or relying on the navigation pane, you can get an instant report with a simple procedure. This is also available for the files in a CASLIB.
Simply run the following code in SAS Studio:
* Connect to a CAS session;
cas mySess;
* Move the results also into tables;
ods output FileInfo=work.file_info;
ods output TableInfo=work.table_info;
proc casUtil;
list files inCASLib = 'Public';
list tables inCASLib = 'Public';
run;
* Terminate the CAS session;
cas mySess terminate;
This code will generate a neat summary table in your results window and also store the result as tables in your work library.
