Because computers do not have the flexibility of reading and translating documents like humans do, it is important to have a standard file format in EDI so that computers can read and translate EDI documents correctly. It is also just as important for users who are processing EDI files to adhere to the EDI standard. One method of enforcing the EDI standard is to validate any incoming EDI documents before they get translated. Validation not only ensures a more accurate EDI translation, but also ensures a more robust automated process by detecting and rejecting EDI files with anomalies that could break the translation program and interrupt production. PassportEDIValidator is a powerful tool that gives its user almost unlimited ability to validate an EDI file. It uses Standard Exchange Format (SEF) files to obtain the EDI file's implementation guideline, which will be used against the EDI file itself during validation. This web page will briefly describe how-and-what PassportEDIValidator validates in an EDI file.
