Confidence-Based Routing to Action Center in Document Understanding (Modern vs Classic)

Hi Team,

We have a requirement in our document processing workflow where:

If a document’s extracted fields do not meet a certain confidence threshold (based on taxonomy / extraction confidence), the document should be sent to Action Center for human review.
If the document meets the defined confidence threshold, it should bypass Action Center and proceed directly to further automated validations and downstream processing.

We would like to understand the best recommended approach for this scenario:

  1. Should this be implemented using Modern Document Understanding activities?
  2. Or is it better to use Classic Document Understanding?
  3. Is there any better or recommended design pattern using the regular DU process to achieve confidence-based routing efficiently?

Our goal is to minimize human-in-the-loop involvement and use Action Center only when required based on confidence thresholds.

Any guidance or best practices would be greatly appreciated.

Thanks in advance!

Hi @82700f925014b7367cdb46a13 ,

Welcome to the UiPath Community.

You can achieve confidence based routing with both Classic and Modern DU activities. The Document Understanding Framework already supports this capability of routing to Action Center based on confidence score of particular fields. So the underlying template will be the same just the way how we configure the classifiers and extractors will be slightly different for Classic And Modern Activities.

If want more info like which project type to use(Classic/Modern), how to use and configure modern activities in the DU Framework, please refer to this- https://docs.uipath.com/document-understanding/automation-cloud/latest

HI @82700f925014b7367cdb46a13 ,
Welcome to the Community,

The recommended approach is to use Modern Document Understanding.
After Extract Document Data, check the document or field confidence (ExtractionResults.DocumentConfidence).
If confidence is below the defined threshold, create a Document Validation Action in Action Center; otherwise, skip validation and proceed with downstream processing.
This aligns with UiPath best practices and ensures Action Center is used only for low-confidence documents.

For Reference:

If its helpful please mark as solution and let me know if you have still persist issue.
Thanks & Happy Automations

Hi @82700f925014b7367cdb46a13

Use Modern Document Understanding.

After extraction, check field confidence:

  • If confidence < threshold → send to Action Center
  • If confidence ≥ threshold → continue automation

Modern DU is recommended (better confidence handling and Action Center integration).

Welcome to the community

Using modern makes sense to make it future proof.IXP is the new way so try the same

Routing and confidence scores checking would be same for both classic and modern though
