Step 4: Set Click-and-Drag Labeling attribute into ³Detect Missing Value.´
Looking closely at the API package table, we see that some packages
have descriptions but some descriptions are missing. We are aware about
this situation very well but the agent¶s data extractor is not. We can tell
the extractor that some values are missing by selecting the ³Detect
Missing Value´ option below the ³Click-and-Drag Labeling´. Selecting
³Detect Missing Value´ option will tell the extractor to automatically
detect missing values and these missing values will be replaced by a
³N/A´ strings which means ³not available´.
