You would like to automate the generation of Time Account Snapshots and would like to check if that would be possible.
SAP SuccessFactors Employee Central (EC) - Time Off
Currently we do not support the automation of this process.
To generate the Time Account Snapshot object you need to execute the Time Account Snapshot Calendar and currently there is no way to automate this execution.
Since this is currently not supported you can suggest this as an enhancement request, please refer to the KBA 2090228 for more details on the process.
For more information about Time Account Snapshots, please refer to Time Account Snapshots.
