Apologizes for the delay in a response!
SIC Would work for this scenario using Smart Integration Functions. You can invoke these to pick-up remote data from file shares up to 500-600mb or so and retrieve them from a OneStream BR. (Simple example below). We cannot tunnel this traffic over SIC using the direct connect capabilities as SMB shares use port 445 when a UNC path is specified and there is not a means to direct that traffic over a SIC managed port. Smart Integration Functions would be the path to use in this scenario -- would this work for your needs?
public class MainClass
public byte RunOperation(string year)
string fname = @"\\someshare\path\hw_" + year + ".csv";
byte buffer = System.IO.File.ReadAllBytes(fname);
