Question: Block Until Done/Change Stream Order

[Czaggy]

Hello everyone, I have been struggling with a problem for a week now - maybe you can help me out :)

I have two streams - #1 should run first and then create the "archive" file in stream #2.

The point is that no matter what tools I use, it will always try to create the output first before reading the input at the bottom.

Is there a way to specify the order in alteryx? I cant seem to find a solution to this.

My desired behaviour is "first read the input" then process the rest- in the end create the archive file (yellow box).

Thank you very much!

Hey @Czaggy,

You can try to use a second Block Until Done tool in the archive path. This will stop again. With multiple BUD tools, the one with the lower ID (Defined by the order the tools are pulled into the canvas) is always executed first.

Hi @Czaggy,

if you are using the last version of alteryx, you can use control containers which will allow you to specify the order.

If not, one trick would be to have make a "fake" join just before the output (which should be done in the second place and joining it to the data from stream one.  If you can send a sample workflow I could do a demo if needed!

the fake join did the trick! Thank you very much :)
