The target file is a flat file where the mapping writes the data after removing the blanks in the beginning and end of string values. Create a customerTrim.csv file as the target file for the target data object.

Use parameters to change the output file name at run time when you use a different data source. The Data Integration Service creates the output file based on the parameter value for the target file name and saves the file to the target directory on the system where Informatica services is installed.
