X Stream provides smooth, quick data transfer from your customer’s system, whether it is Windows® based or not, and from virtually any manufacturer. 

An X Import preprocessor is at its most basic an executable that accepts a filename as its first command-line argument.  It then performs data aggregation or transformation and outputs data to STDOUT in a format that can be processed by X Import.

Workflow

• X Import reads in all the configuration files from its working directory set.
• X Import monitors a directory for files (DataPath).
• If a file is found that matches the extension (DataMask) then the file is selected for processing.
• If the configuration file specifies a preprocessor, then pass the current filename to Ratepreprocessor and use the data returned by the preprocessor for further parsing.
• Once the file (or preprocessor output) is read, data is parsed according to the configuration file.
• X Import iterates through input file, building an internal list of orders or route stops.
• X Import iterates through its internal list of orders/stops and posts them to XMLListener (see Posting Process below)
• When X Import has attempted to place all orders/routes, it creates an audit log which is available in X Dispatch through X Stream > Import Audit Log.
