Teradata Error: 3807 - Updating a View - response (1) by anandc

Its very strange... I removed the Alias name from the Select statement in the View DDL and it worked...
Previously my DDL was like
REPLACE VIEW <VIEWNAME>
(Col1, Col2, Col3....) as
SELECT
(f.Col1, f.Col2, f.Col3...)
FROM <TableName> as f
 
Now
REPLACE VIEW <VIEWNAME>
(Col1, Col2, Col3....) as
SELECT
(Col1, Col2, Col3...)
FROM <TableName>
 
What difference did this make so i was not able to UPDATE the column
Can some one please help me understand why it was not working with the Alias Name in the select...
Thanks !
