Sales-Con-201 Data Management Practice Question
A Consultant is loading Campaign Members into Salesforce. The CSV contains Contact IDs and Campaign IDs. Some rows fail with a 'Entity failed validation' error. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Contact is already a member of the specified Campaign, violating uniqueness.
Campaign Members have unique constraints; attempting to insert a duplicate Contact/Lead into the same Campaign will trigger validation or database errors.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Campaign records must be locked before adding members.
Why it's wrong here
Locking campaigns is not a prerequisite for adding members.
- ✓
The Contact is already a member of the specified Campaign, violating uniqueness.
Why this is correct
A Contact or Lead can only exist once per Campaign, causing duplicate membership inserts to fail.
- ✗
Campaign Status is a required field that was omitted from the mapping.
Why it's wrong here
While status is important, default values typically apply if omitted; duplicate membership is the primary failure cause.
- ✗
Campaign members cannot be loaded via Data Loader; they require Data Import Wizard.
Why it's wrong here
Data Loader fully supports Campaign Member inserts and updates.
