There are several transformers with Reject ports. Sometimes features with smaller problems pass through the normal ports but may caise problems later. Eg: reading Excel files by FeatureReader the log warns:
Excel Reader: Sheet 'Sheet1' of dataset '\\bmbcradicon1c$IconImportsRejected Direct DebitsDD Rejections 131017.xlsx' has column 'A' that does not match a header column in the file. This column will not be produced
The features go through the workspace and all of them are filtered out unsuspected as there is no Column A.
For these cases it would be nice to have an option to send features with any warnings to the Rejected port.
