Create Custom Schema for Custom Documents

1. Open the Document Information Extraction Trial UI, as described in the tutorial: Set Up Account for Document Information Extraction and Go to Application.

   If you HAVE NOT just used the Set up account for Document Information Extraction booster to create a service instance for Document Information Extraction Trial, and subscribe to the Document Information Extraction Trial UI, observe the following:

   • To access the Schema Configuration and Template features, ensure that you use the blocks_of_100 plan to create the service instance for Document Information Extraction Trial.

   

   • And make sure you’re assigned to the role collection: Document_Information_Extraction_UI_Admin_User_trial, or the combination of the role collections: Document_Information_Extraction_UI_End_User_trial and Document_Information_Extraction_UI_Templates_Admin_trial. For more details on how to assign role collections, see step 2 in the tutorial: Subscribe to Document Information Extraction Trial UI.

   

   • After assigning new role collections, Log Off from the UI application to see all features you’re now entitled to try out.

   

2. To create a custom schema, click the wheels icon and choose Schema Configuration.

   

Here, you find the pre-defined SAP schemas, one for each of the standard document types that are supported by Document Information Extraction out of the box. You can’t delete or edit SAP schemas, but you can see and Copy the information they extract from documents.

CAUTION:

Be aware of the following Document Information Extraction Trial UI trial account limitations:​

• Maximum 40 uploaded document pages per week​ (the documents can have more than 1 page)​
• Maximum 10 schemas per trial account
• Maximum 3 templates per trial account (with a maximum of 5 sample documents each)

To create your own schema, click Create and a dialog opens.

In the dialog, enter a name for your custom schema, Custom_power_of_attorney_schema, for instance. Note that the name cannot include blanks. Further, select Custom as your Document Type.

Click Create to create the schema.

Now, your schema shows up in the list. Access the schema by clicking on the row.

To define your first header field, click Add.

For each custom field, you have to enter name and data type. The potential data types are string, number, date, discount and currency. Default extractors are not available for custom documents. Adding a description is optional.

As your first header field, add the shipper number of your power of attorney document.

1. Enter an appropriate name for your field, shipperNumber, for example.

2. Select string for the Data Type. Note that a shipper number is a string, even though it consists of numbers, as it is an arbitrary combination of numbers without meaning. In contrast, price is an example for the data type number.

3. Click Add to create the header field.

   

The field now displays in your list of header fields where you find all the information again that you have just entered. You can edit or delete the field by clicking the respective icons on the right.

Click Add again to open the Add Data Field dialog.

1. Enter a name for your second header field, fullName, for example.

2. Select string for the Data Type.

3. Click Add to create the field.

   

Go ahead and create the list of header fields as shown in the table and image below. Pay attention to the different data types. Feel free to extend or reduce the list of header fields.

Once you have added all fields, the schema needs to be activated so that it can be used to extract information from documents. Right now, the schema has the status PASSIVE, indicating that it cannot be used yet.

To activate the schema, click Activate.

Now, the status of your schema changes to ACTIVE. To make changes to your schema, you have to Deactivate it first.

Congratulations, you have created and activated your first custom schema for power of attorney documents.

In the next tutorial: Create Custom Template for Custom Documents, you’ll create a template that uses your schema and add sample documents to show the Document Information Extraction service where each field is located in the document.
