FVU is a program developed by NSDL, which is USED to ascertain whether the e-TDS/TCS return file contains any format LEVEL error(s). When you pass e-TDS/TCS return through FVU, it generates an ‘error/response file’. If there are no errors in the e-TDS/TCS return file, error/response file will DISPLAY the CONTROL totals. If there are errors, the error/response file will display the error location and error CODE along with the error code description. In case you find any error, you can rectify the error and pass the e-TDS/TCS return file again through the FVU till you get an error-free file.
