Customizing Extraction Fields in SAP Document Information Extraction (DOX)

[kevinkim0908]

Hello, 

I’m currently evaluating SAP Document Information Extraction (DOX) in SAP Document AI using a trial account. Although I’ve noticed that it extracts every text very accurately, not every text is being mapped to the extraction fields.

I wanted to add/customize header fields myself to map the extracted text to header fields or line items better (while following this link https://help.sap.com/docs/document-ai/sap-document-ai/add-data-fields to add data fields) but schema configuration doesn’t appear in my trial environment. It also states that I cannot change SAP schemas as shown in the attached image below:

So I was wondering if it's possible to edit/customize extraction fields in the premium version of SAP Document AI? If so, does this customization occur before the optical character recognition (OCR) to guide the model, or only after OCR to map extracted text to fields?

Defining custom field mappings before OCR would be extremely valuable for my team's use case, so I’d greatly appreciate if anyone can explain what’s possible before I consider upgrading to a full subscription. Thank you.

Hi @kevinkim0908 

Thank you for your question

Yes, it is possible to edit or customize extraction fields in the premium version of SAP Document AI. To your second question, yes, customization and schema editing happen after Optical Character Recognition has processed the document text. Premium tiers also support enhanced features like user correction feedback loops for progressive refinement and schema extensibility for your specific business needs.

Considering that customization to map extracted text to your header fields or line items is critical for your team, I recommend you upgrade to the Premium version. Check below links for more information.
