Does the Windows TA nullify the Windows field called Error Code?

[danielbb]

It's similar to Windows TA not Parsing "Error_Code" from 4776 Logs

My take on that is -

The TA does the following - if a field by the name Status (Windows field) exists, its value is being copied to a new field called Error_Code (Splunk field). If Status has no value, Error_Code would have a dash (-). So, it's a field alias.

Now, if Error_Code existed already as a Windows field, then Error_Code would be overridden by the value of the Status field or a dash.

So, we end up losing lots of data.
