We have a Roll-Up Summary field. It's a SUM aggregation of a field on custom childs of Opportunity. The field is set to "Automatic calculation (Recommended)". It usually works fine. For example if we Clone or create an Opportunity the field is correctly calculated to 0.
However when we "Clone with Related" the Summary field is left blank. Where is the difference in the inner workings of Salesforce when using the deepclone action?
Is there a way to force the recalculation other than adding a dummy child and removing it afterwards?
