A Conditional split will do what you need here. Just write your condition for error records to have blanks in any of your requried fields (i.e. if name and password and dept are all required, then the condition:

isnull(name) || (len(trim(name))==0) || isnull(password) || (len(trim(password))==0) || isnull(dept) || (len(trim(dept))==0)

would be the condition (if you use the defaults that come up in a conditional then this condition would be Case 1) for the Error rows.

In your flow, direct the arrow for Case 1 to your ERROR_USERS table write process, and the arrow for Conditional Split Default Output to your USERS Table.
