When sharing an interview (Document Services) it might be necessary for the sender to input certain fields before sending the interview to the recipient. This is when the ValidateBeforeShare command is important.
Other fields on the interview may be marked as Required, e.g. the EmailAddress as shown above, but the Required validation is only done on the assembly of the document. If it so happens that fields MUST be completed by the sender before they can be allowed to share the interview, then use the ValidateBeforeShare command. This will ensure that any validation on those data elements is executed before the interview is shared.
