3692467 - Exposed interface function argument info not synced after changing the argument for the source function in SAP Analytics Cloud (SAC)

1. Auto-expose function inside script object, where the function argument is of string type.  
2. Modify the function argument info (ID, type, or 'set as array') in the original function.  
3. Access the builder panel of the auto-exposed interface function.  
4. - Observed behavior: The argument info of the auto-exposed interface function does not sync.  
   - Expected behavior: The argument info of the auto-exposed interface function should sync.  

SAP Analytics Cloud

1. Auto-expose a function inside a script object, ensuring the function argument is of string type.
2. Modify the function argument info (ID, type, or set as array) in the original function.
3. Open the builder panel of the auto-exposed interface function. 

This is a known issue.

The fix will be released to the customer tenant with SAC version 2026.02.
However, please note that while this fix will prevent the issue from occurring in the future, it will not automatically resolve inconsistencies in composites that are already inconsistent. 

To address the existing inconsistency, please:

1. open the original scripting function
2. toggle off and toggle on 'Expose in stories as interface function,' which will delete the existing interface function and recreate it with the same argument info as the scripting function.
