Okay, I’ll try to explain as good as I can… Quite a particular case.

Okay, I’ll try to explain as good as I can… Quite a particular case.

Tools: SSIS 2008

We have a control flow that now needs to be triggered by an event: the presence of one or multiple files. (1,2 or 3)

The variables used:

BO_FileLocation_1
BO_FileLocation_2
BO_FileLocation_3
BO_FileName_1
BO_FileName_2
BO_FileName_3

There can be one, two or three files: defined in above variables. When they are filled in,
they should be processed. When they are empty, this means there’s just one file file, the process should ignore them and jump to the next (file watcher?) task.
For example:

BO_FileLocation_1= "C:\"
BO_FileLocation_2 NULL
BO_FileLocation_3 NULL
BO_FileName_1= "test.csv"
BO_FileName_2 NULL
BO_FileName_3 NULL

The report only needs one file.

I’d need a generic concept that checks the presence of these files, it could be more generic than my SSIS knowledge can handle right now. For example handy, when there’s a 4th file in the future. I was also thinking to work with a single script to handle all the logic.

Thanks in advance

    If all you want is to trigger the Copy Source File to handle if one or more of the files is present, just use the OR Constraint in your flow. The following image shows you how:

    First connect all to the destination:
    Original layout

    Then click one of the green arrows. This will make its properties window pop up. Select the Logical ORinstead of the Logical AND:
    precedence constraint properties

    If everything went well, you should now see the connections as dashed lines:
