Rollup summary fields are often created only on master objects in master-detail relation. Rollup summary is used for applying aggregate functions on corresponding child records.

Count():  This will return count of the number of records of children which are participating in the rollup operation.

sum(Number/Currency/ Percent): This is utilized or used to make the summarized value of given child records participating within the rollup.

Max(Number/Currency/Percent/Date/DateTime):  This is used to return the maximum value from the corresponding child records participating within the rollup operation.


  • This will return the minimum value from the corresponding child record which is participating within the rollup operation. 
  • We can create the filter condition to specify which child records should participate within the rollup operation.
  • Allow all the child records:
  • If this is chosen all the records of the child of the master record will participate within the relation.
  • Allow only those records of child which are meeting the filter condition: 
  • If this is chosen, only those child records which are meeting the filter condition can participate within the relation. We can create 25 rollup summary fields on an object.
