Use Skill activity - ABBYY Documentation

Use Skill is typically the first Vantage activity in a UiPath workflow. It submits a document to a Vantage skill and hands back a Transaction Id. Processing happens asynchronously inside Vantage. You pass the Transaction Id to the Get Results activity to fetch the results once processing finishes.

Activity properties

Group	Property	Type	Description
Connection Settings	Skill Name	`String`	The name of the Vantage skill.
Input	Input Files	`IReadOnlyDictionary<String,InputFile>`	A Dictionary collection, where `String` is the file name and `InputFile` is the class describing the input file. Each `String` key must be unique, so you cannot add two files with the same name.
Input	Transaction Registration Parameters	`IReadOnlyDictionary<String,String>`	A Dictionary collection of transaction registration parameters to pass the key and value of each parameter.
Output	Transaction Id	`Guid`	The identifier of the created transaction. This ID is then used as the Transaction Id input property of the Get Results activity to get the status of the transaction and the processing results.

InputFile

Name	Type	Description
fileStream	`Stream`	The contents of the file that will be passed to ABBYY Vantage. You can pass the stream of the file on a local disk as a value of this property (e.g. `System.IO.File.OpenRead("D:\images\Invoice1.pdf")`).
index (optional)	`Integer`	The index number of the file in the transaction.
fileRegistrationParameters (optional)	`IReadOnlyDictionary<String,String>`	A Dictionary collection of file registration parameters to pass the key and value of each parameter.

Select a skill

The Use Skill activity can only be used inside a configured Vantage Scope activity.

Set the credentials

On the Vantage Scope activity, set the Password or Client Secret property, depending on your authentication flow. This lets the connector retrieve the skill list. Once the workflow is configured, switch to the Secure Password or Secure Client Secret property. For more information, see Vantage Scope activity.

Load the list of skills

Click the button to the right of the drop-down list under Skill Name.

Choose the skill

Expand the Skill Name drop-down list and select the skill to use for document processing.

The Skill Name parameter accepts a UiPath String variable. Selecting a skill from the drop-down writes the new value to the variable. Expressions and references to other variables are not supported.

Reduce the file size of large files to 30 MB or less to speed up document processing.
