Hello,
I'm currently working with Data Services 4.0 and the client is asking for a file existance validation.
This is my first time working with this tool so i still don't know it very well.
I found a blog where someone explains how to check if a file exists...the issue here is that i'm not sure about how to implement it or add it to the DataFlow... i'm not sure if i have to use try-catch or how to create the whole process.
If someone could explain or tell me how to do it, i'll be eternally grateful
PS. This is the link that explains how to check if a file exists:
