The correct order of steps in the Document Understanding processing flow for a generic document is as follows:
1. Digitize: The first step involves digitizing the document to turn it into machine-readable content.
2. Classify: Next, the document is classified to determine the types of documents found within the digitized file.
3. Data Extraction: After classification, the relevant data is extracted from the document.
4. Data Export: Finally, the extracted data is exported for consumption1.
This sequence ensures that the document is first made readable for the system, then categorized, followed by data extraction, and concluding with the export of the data.
