### Problem

VaultSpeed automatically ignores columns that match the name specified in the **CDC_TIMESTAMP** parameter. So if the parameter value is set to `updated_on` and you have column `updated_on` in your source data model this column gets ignored. This becomes unexpected behavior when you set your source CDC to "Full Load". It is ignored regardless.

### Solution

As a workaround, you can un-ignore the column just after the source model was retrieved:

- Open the source model and uncheck ignored.

(notice we now get that error, we will fix it in the next step)

- Go to source parameter settings and change the **CDC_TIMESTAMP** parameter value to something that does not match your column name.

- Go to the source model to validate that column is now included as expected and there is no error.

> ℹ️ If you know ahead of time that the source will contain columns that will match **CDC_TIMESTAMP** parameter value, update it ahead of time. This way columns will not be ignored in the first place.
