Missing Input Link on Component

Anonymous — Fri, 24 May 2019 04:30:10 GMT

Hi Forum,

I've been trying to find the solution for this problem and thought it would be fairly easy but I can't find an answer.

I've created a job as follows;

tFileDelimitedInput >> tUniqRow >> tReplace >> tMap & all works OK.

Now I want to reuse it with another datasource replacing the existing tFileDelimitedInput.

So I have deleted the Component & the Link between tFileDelimitedInput and tUniqRow also was deleted.

When I go to join the new source to the tUniqRow, it won't join.

The error is "Warning, there is no Input link"?

I've read someone say to change the 'Startable' setting on the component to 'True' but can't find this setting anywhere?

I've also read that I could join the link to another component and move it back after I have the new data source.

Can someone advise how I can reinstate the input link so I can connect my data?

I'd also like to know why Talend behaves this way, as it seems counter intuitive to me?

Thanks

What is the type of the new component you are using?

Can you attach a screenshot of your job?

As I advised, in this case it's the tUniqRow Component, but it happens on various Components.

I'm trying tofind out why Talend does this?

Thanks

Hi,

If you would like to retain the source schema for a tUniqrow from one source to another, you need to do the following method.

Below I have created a sample flow with three columns.

The link at the tfileinputdelimited_1 is selected and I dragged it into new source tfileinputdelimited_2

You can see that the link got transferred along with column details to new source.

Thanks Nikhil !!

That's going to save me loads of time & grief.

I also appreciate that you took the time to show pictures of what you mean step by step rather than just posting a link or assume things.

Well done and thanks again.
