To do this in Azure Form Recognzier, we need to first identify the documents (purchase orders, invoices, quotations, etc.) that we want to write.
We are aware that we need to create a model that corresponds to the

Hello @test29998411

Thanks for reaching out to us, I think you are looking for "Composed model".

A composed model is created by taking a collection of custom models and assigning them to a single model comprised of your form types. You can assign up to 100 trained custom models to a single composed model. When you call Analyze with the composed model ID, Form Recognizer will first classify the form you submitted, choose the best matching assigned model, and then return results for that model.

You can create your composed model with all types of forms. When you input your new form, the model will choose the best model for your form and do the analyze. Please check below guidance on how to do it.
