This parameter tells the writer whether it should ignore features that would usually cause the translation to fail. This includes features that are topologically incorrect, are not supported by the Geodatabase writer, or conflict with the definition of the table to which it is to be inserted (that is, they are outside of the geometry envelope specified by the feature class). Additionally, the writer will also ignore polygons, donuts, or aggregates of polygons/donuts that cannot be reoriented.
The default setting is No, which means that failed features are not ignored and will cause the translation to fail when encountered.
If this parameter is set to Yes, the three other associated parameters (described below) are enabled: Max Number of Features to Ignore, Dump Failed Features to File, Failed Feature Dump Filename.
