The Salesforce administrator needs to configure Roll-Up Summary fields on Delivery Manifest to aggregate shipment data. Which two operations can a Roll-Up Summary field perform on the related child records? (Select 2)

  2. Find the MIN or MAX value of a date or date/time field among the child records.Answer
  3. C
    Summarize field values from child records connected using a Lookup relationship.
  4. D
    Retain detail records independently when the parent master record is deleted.

Answer

Roll-Up Summary fields can calculate the total SUM of numeric fields and determine the MIN or MAX value of date or date/time fields on related detail records in a Master-Detail relationship.
Roll-Up Summary fields allow administrators to calculate aggregate values—specifically COUNT, SUM, MIN, and MAX—from detail records in a Master-Detail relationship. Calculating a SUM of numeric fields and finding MIN/MAX dates are both core supported operations.

Step-by-Step Solution

1
Identify relationship requirements for Roll-Up Summary fields.
Confirm that Roll-Up Summary fields are only allowed on the master object of a Master-Detail relationship.
Salesforce standard functionality restricts declarative roll-up summaries strictly to Master-Detail parent objects.
2
Evaluate allowed aggregate functions.
Identify COUNT, SUM, MIN, and MAX as valid calculations.
SUM applies to numbers, currency, and percentages, while MIN and MAX work with numbers, currency, percentages, dates, and date/time fields.
