The Planned_Calls_vod__c field on the Cycle Plan record shows a different value than the total Planned Calls on Cycle Plan Target list.
There are Cycle Plan Target records where no Target (Cycle_Plan_Account_vod__c) is specified.
The Planned Calls Roll-Up Summary field counts them, but as no Accounts are assigned to these records, the Cycle Plan Target list does not calculate them.
You can use the following SOQL query to determine the affected Cycle Plan Target records where Targets are missing:
SELECT Cycle_Plan_Account_vod__c,Id FROM Cycle_Plan_Target_vod__c WHERE Cycle_Plan_vod__c = »Record ID«
Add Target (Cycle_Plan_Account_vod__c) to the affected Cycle Plan Target records.
