@Vijayakumar R Thanks for the question, Can you please add more details about the input data and share the response that you are getting, also Is it prebuilt or Layout or train w/labels that you are trying?
If you are extracting only text, tables and selection marks from documents you should use layout, if you also need to extract key value pairs you can train a custom model or use a pre-built (Invoice, Receipts, Business Cards).
Layout results (text, tables and selection marks) are included in all the Analyze outputs (custom and pre-built) in the readResults (text) and pageResults (tables) of the JSON output.
• Layout – extract text, tables selection marks no training required
• Pre-built – Invoice, Receipts, Business Cards – extract values of interest from these type of documents
• Custom – Extract key value pairs trained on your own documents
