About the Document Understanding activity package

The UiPath.DocumentUnderstanding.Activities package enables the usage of a complete document processing framework, from taxonomy definition, digitization, document classification, data extraction, and data validation.

note

The namespace of UiPath.DocumentUnderstanding.Activities is UiPath.IntelligentOCR.StudioWeb.Activities.

Known limitation​

If you are using "Wait for" type activities that suspend workflows and you are working with DataTable variables, it is crucial that DataTable variables are serializable. For example, if a DataTable variable is initialized with new System.Data.DataTable, then it becomes non-serializable, and this can cause your project execution to fail. To prevent this, you can either: leave the default value of the DataTable variable empty, or assign a name to the DataTable variable, such as: new System.Data.DataTable("MyTable").

Activity packages compatibility​

UiPath.IntelligentOCR.Activities and UiPath.DocumentUnderstanding.Activities should not be used together in the same project. The UiPath.IntelligentOCR.Activities package should be used for Windows (or Windows-Legacy) workflows, while the UiPath.DocumentUnderstanding.Activities package should be used for Windows and Cross-platform workflows.

note

Before using the Monitor feature, take into consideration the following:

  • Only UiPath.DocumentUnderstanding.Activities v 2.7.0 or newer versions support Monitor;
  • Only IntelligentOCR.Activities v6.20 or newer versions include the Document Understanding Project Extractor activity which supports Monitor
