I want to have only the value of the picklist saved in the field composed of the picklist.

On the current Eloqua system, even if the field is configured as a picklist, if you make a mistake in Field Mapping in Form Processing or if you make a mistake in mapping when uploading, a value other than the picklist value is saved.

By the way, I would like to set the data not to be stored incorrectly, such as SFDC, from the beginning, non-picklist value.

What can I do?
