Thread: Switch doesnt work as expected... Alternative?

  1. #1

    Default Switch doesnt work as expected... Alternative?

    I have 2 files

    File A is always present (csv)
    File B is sometimes present (xlsx)

    is there a way to choose with path to use depending on if File B is present?
    Essentially, File B is used to filter (Xref) File A... then that output is used.. but if not there, then Just use File A

    The Excel node, by itself, will fail if you specify a hard-coded name for a file that doesn't exist.
    The way around that is to use a DirectoryList node in front of it - that way Excel will simply return zero records

    Then, create a dummy StaticData node that has the columns you require from the Excel, and use the CAT node to force those columns into the stream.

    Attached is a sample.

    that part is all fine.. i am using it. the problem is after it.

    CSV file > Filter > Filter > Sort \/>--------------->Switch> output
    | |
    | |
    |---- XREF ---------
    XLS file > -------------Sort--------

    i couldn get an image to work.. lol

    CSV to the switch always wins so it just goes thru..
    I need it to take the XREF path with the XLS file has data/exists

    Can something go in between the CSV sort and switch that will disable if the XLS file loads?

    wait got it... in the picture case it should only use the APFEED file..

    here it should use the XRef path

    Only way it works so far is to use a sleep timer, which is not going to be reliable.
    i mean, i suppose I could use a metacheck.. but then to have to entirely different streams would be crazy. a LOT happens outside of the starting composite

    well i got it to work by going even higher up. I took Scenario A and put it into a composite
    and Scen B in another...
    then the Directory and file checks feed to 2 metachecks for a certain field.. each feeds into its own composite.
    While its not ideal, it works! lol
