4. Copy the data transform into your ruleset:
   1. On the rule form header, click Save as.
   2. On the Save as Data Transform rule form, in the Context section, in the Add to ruleset list, select a ruleset to store the data transform.
   3. Click Create and open.
5. On the Definition tab, click Add a row.
6. In the Action column, select Set.
7. In the Target column, enter the property that you store in Pega Process Fabric Hub.

   For example: Enter .region.
9. Optional: To add more properties, repeat steps 5 through 8.
10. Click Save.

For example: The following figure shows the PopulateAdditionalFields data transform that maps the .region property from the remote application to the .location property from Pega Process Fabric Hub:

As a result, Pega Process Fabric Hub can display error messages that include property names from the remote application, so that you can quickly identify and investigate a property that fails validation.

1. Provide validation for assignment fields:

   Choices	Actions
   If you use standard validation logic for your properties, configure the ValidateAdditionalFields validate rule.	In the navigation pane of Dev Studio, click Records. Expand the Process category, and then click Validate. In the list of validate rules instances, click the ValidateAdditionalFields validate rule that applies to the PPF-Data-Ext-Task class. On the validate rule form, click Save as. On the Save as Validate rule form, in the Context section, in the Add to ruleset list, select a ruleset to store the validate rule, and then click Create and open. On the Validate tab, create validation for your properties with required conditions. For more information, see Validating field input in complex scenarios. On the Validate form, click Save. For example: The following figure shows a validation for the .Region property. The validation states that the only allowed values are North, South, East, and West. If users provide an incorrect value, Pega Process Fabric Hub displays an error message.
   If you use advanced validation logic for your properties, configure the ValidateAdditionalFields activity.	In the navigation pane of Dev Studio, click Records. Expand the Technical category, and then click Activity. In the list of activity instances, click the ValidateAdditionalFields activity that applies to the PPF-Data-Ext-Task class. On the activity rule form, click Save as. On the Save as Activity form, in the Context section, in the Add to ruleset list, select a ruleset to store the activity, and then click Create and open. Modify the validation method for your property. Modifications of the ValidateAdditionalFields activity depend on your unique business scenario. For more information, see Configuring steps in an activity. On the ValidateAdditionalFields activity rule form, click Save.

2. Configure the MapToAPIFields decision table:
   1. In the navigation pane of Dev Studio, click Records.
   2. Expand the Decision category, and then click Decision Table.
   3. In the list of decision table instances, click the MapToAPIFields decision table that applies to the PPF-Data-Ext-Task class.
   4. On the decision table rule form, click Save as.
   5. On the Save as Decision Table form, in the Context section, in the Add to ruleset list, select the ruleset to store the decision table, and then click Create and open.
   6. On the Table tab, in the Field name column, enter the property from Pega Process Fabric Hub that you want to validate.
   7. In the Return column, enter the matching property from your remote application.
   8. Optional: To map more properties, on the toolbar click Insert Row After, and then repeat steps 2.f and 2.g.
   9. Click Save.
   Result: For more intuitive debugging, Pega Process Fabric Hub displays the property name from your remote application in the error logs, as shown in the following figure:
