Consider the following rules and guidelines for Cvent tasks:
•You cannot preview data when you read data from the ContactSnapshot object.
•You can read data from the following child objects when the ContactSnapshot object is selected as a parent.
- ContactGroupDetail
- DistributionListDetail
- CustomFieldDetail
•You can select a child object only when the source type is selected as multiple objects.
•You can access the CutsomFieldDetail child object only when relationship.ini and schema.ini are configured accordingly. For more information about how to configure the Schema.ini and Relationship.ini file to read data from Cvent custom fields using Cvent Connector in Data Integration, see https://kb.informatica.com/howto/6/Pages/22/564698.aspx
•You can process only a limited number of Cvent objects in one SOAP call, as Cvent limits the rows processed within a single call. For more information, see Call Specific Limits.
