Salesforce Error FIELD_CUSTOM_VALIDATION_EXCEPTION — How to Update The Validation Rule


A user is experiencing an error when synchronizing events or appointments.

Sample error message from Riva Cloud or Riva On-Premise:

Error 1

2013-05-05 09:39:18,885 INFO [CTP-wmw #1] [1TYHF17KWOHS] [CA] Updating item: Test invite [00Ub0000001FmKLEA0]

2013-05-05 09:39:20,854 ERROR [CTP-wmw #1] [1TYHF17KWOHS] Error occurred updating item: [FIELD_CUSTOM_VALIDATION_EXCEPTION] You need to choose one or more contacts who will attend this meeting. Use the Look-up and enter the contact name and press Search or press Search -- WhoId

Error 2

Error-[FIELD_CUSTOM_VALIDATION_EXCEPTION] The subject field cannot exceed 80 characters in length...


Error 1:

Salesforce allows specific fields to be validated, but not all fields are available during the synchronization. For error 1, Riva encountered the FIELD_CUSTOM_VALIDATION_EXCEPTION error while updating an Event record. The Salesforce validation rule failed for the field WhoId.

Error 2:

For error 2, Riva encountered [FIELD_CUSTOM_VALIDATION_EXCEPTION] The subject field cannot exceed 80 characters in length...error while updating an event record. The custom field has been set to the 80-character maximum in Salesforce.


Solution for error 1

Not all validation rules are appropriate for the synchronization process, especially in scenarios where the sync process has no way of knowing the information that is being required. Examples of these are fields that do not exist in a default address book, like annual revenue or the number of employees — these types of fields should not be required for Riva to sync. If Salesforce requires them, they should be left up to the next record editor to complete, or another process should be defined to handle them.

The following solution works for both platforms of Riva (Cloud and On-Premise).

To make a Salesforce field not required during sync:

  1. Identify the field that is causing the validation exception.

    The field is named in the error message. In the sample error message 1, it is "WhoId".

  2. In Salesforce, edit the validation rule to exclude the validation for the Riva sync user.

    The following example skips the validation rule if the user that has logged in to Salesforce is the Riva sync user '':
