Exactly! That's what I was referring to. Good to hear that it was helpful

Thanks Preet, I'll check out the AI Document Center. Thank you so much.

That's great to hear! Again, AI Document Center is a solution that helps you do this and much more. It walks you through the model configuration, allows you to test and validate multiple documents and use the extraction model directly in your business process.

Hi Shubham, I now understand which AI Skill option you were referring to with unstructured documents. I hadn’t seen that option before, but I’ve now configured it, ran some tests, and was able to extract the data from the table.

Thank you very much.

Hi Preet,
Got it — let me review the AI Document Center solution to see if I can use it to extract the table data from my documents.
Thank you, I appreciate it!

Hi Shubham,

I’m not sure if I understood correctly, but you mentioned that a quicker solution would be to create a new AI Skill using unstructured document extraction. However, that’s actually what I already did.

I created an AI Skill for document extraction and built several models for testing. I first created a couple of unstructured models, and then a couple of structured ones. In both cases, I uploaded more than 25 PDFs, and the table structure matches exactly what’s in the document — with the same field names — but it still didn’t work.

In none of the models was the table successfully extracted.

Víctor Valenzuela I agree that using the Generative AI Skill is a good idea as it is flexible to changing formats and working with complex tables. In fact, we have an intelligent document processing solution backed by these AI Skills that was released in 25.2 called the AI Document Center to serve this exact need and a lot more. The documentation lists how you can set up an extraction model and extract from tables. Please let us know if that helps!

AI Skill may not extract table data if the tables are not clearly machine-readable, or the headers do not exactly match the expected field names. Also, don't allow manual labeling of tables during training - "you won't label the fields in the items table, but that information will still be extracted" automatically by the pre-trained model. However, the model doesn't recognize the unique format of the table in document.
The quickest fix is to create a new AI Skill using "Unstructured" document extraction with a specific prompt to extract the table(Extract the complete table from the document, including all columns: clave, descripción, fecha inicio, and porcentaje).
Alternatively, ensure your structured extraction has the table field set as type "Table" (not Text), properly named nested fields, and at least 50 training documents. Since the pre-trained model wasn't designed for this document, unstructured extraction with targeted prompts will give you better immediate results than relying on automatic table detection.
