How to updating data on CAS in SAS Viya?

[Derick]

I'm using SAS VA via SAS Viya.  I import a dataset into CAS using import wizard.   I import again the latst dataset and choose replace but it gave me an error

BASE Data Connector failed.

The table xxx exists as a global table in caslib Public. By adding a session table with the same name, the session-scope table takes precedence over the global-scope table.

BASE Data Connector failed.

BASE Data Connector failed.

The action stopped due to errors. code: 2-0-4290001

What is this error?

How I can update the dataset on CAS with latest dataset? 

Thanks

Finally found the cause, the latest dataset file was corrupted.  Generate again the dataset file and re-upload it.  Success uploaded.
