Overview:
A Lookup field propagates field values from a parent or referenced object to a child object, referring object, or document. In this case, the Study Type lookup field is not populated with a value on a document even though the related object Study is populated.
Root Cause:
There are two fields with duplicate labels defined in the object and the undesired custom field is selected for the lookup field. In this case, study__type__c is selected when introducing the lookup field.
Solution:
The admin needs to follow the steps below to ensure the expected lookup object source field is selected:
- Go to Admin --> Configurations --> Objects --> [Object] --> [Object Field]
- Rename label of the field.
- Go to Admin --> Configurations --> Document Fields --> [Document Field].
- Select the expected lookup source field.
