Source file directory

to the following directory on the Data Integration Service machine:

The Data Integration Service searches for the source file in the server directory on the machine that runs the Data Integration Service. The server installation contains a copy of the tutorial files. The Data Integration Service cannot read files from the client installation directory unless you change access permissions on the source file and directory.

The following figure shows a sample source file directory:

The Developer tool machine must have access to the source file directory on the machine that runs the Data Integration Service. If the Developer tool cannot access the source file directory, the Developer tool cannot preview data in the source file or run mappings that access data in the source file. If you run multiple Data Integration Services, there is a separate source file directory for each Data Integration Service.
