Error : If this component has output, there must be an input link to propagate the data - tFileFetch

[Anonymous]

I'm trying to apply some aggregation on the output of tFileFetch component but getting an error as mentioned in the subject after running the job. Below is the screenshot : 

Any work around for this error ?

I think tFileFetch should have an input link. You can do something like,

tJavaFlex -->tFileFetch --> tAggregareRow

Hope it helps.

tFileFetch doesn't pass along the contents of the file it retrieves. To work on the file, connect tFileFetch to a file input component with a trigger link. Then connect the file input component to tAggregateRow.

Thank you guys for your reply.

@cterenzi I've tried setting trigger, but didn't get what component and which condition to use. Could you please elaborate ?

Right-click on tFileFetch, Trigger -> On SubJob OK, click on your file input component.

@cterenzi Thanks for the reply.

Do you mean tFileInputDelimited by file input component ? Or any other component ?

As tFileInputDelimited require file name/stream and schema to be defined, how can I achieve that ?

UPDATE :

After research for a while, I got this :
