Hi Zane,

Please recheck the table has an identity column. You may run the following query to get the tables that have identity columns. If the table does not exist in the result, the Create identity token checkbox will not be visible which is expected.

SELECT 
  [schema] = s.name,
  [table] = t.name
FROM sys.schemas AS s
INNER JOIN sys.tables AS t
  ON s.[schema_id] = t.[schema_id]
WHERE EXISTS 
(
  SELECT 1 FROM sys.identity_columns
    WHERE [object_id] = t.[object_id]
);

Or you may use custom query activity to insert data with

Select SCOPE_IDENTITY() as XXX;

 to get the new identity token if you are using a SQL Server. XXX is the token name that you can renamed.

Thanks,

Zhujie
