Flags all columns as not modified.
Column values will not be reset or modified in any way.
This method is defined in the generated record code.
public void ResetToUnmodified()
If original value tracking is enabled, then the current values will be considered the original values after calling the ResetToUnmodified method. Just as if those values were freshly received from the database.
In other words, you are telling the record that "the values in the record match the values in the database"
