System.SObjectException: Field xxx is not editable

System.SObjectException: Field Score__c is not editable
Class.RollupEvaluator.RecursiveUpdateEvaluator.matches: line 637, column 1
Class.RollupEvaluator.CombinedEvaluator.matches: line 90, column 1

when running a MDT rollup against a lead from custom child object I am presented the above exception. the field in question is of type Formula (Number)

the code
clonedItem.put(this.metadata.RollupFieldOnCalcItem__c, calcItem.get(this.metadata.RollupFieldOnCalcItem__c));
seems to be setting the field to manage recursion tracking?

I don't quite follow but obviously what I would like to know is how do I get this roll up to work? Do i need to replicate the field somehow, or is this not even possible with rollup? or is there some further config I can do

Please ask questions as I don't know what information you might need here. I also had a read through the doco and couldn't see anything that mentioned my situation?

Hey @mickster04, thanks for reporting this. I will fix this tomorrow morning, also as part of the v1.2.17 release. Apologies that you’re running into this issue; for now you can get this working by commenting out line 49 in RollupEvaluator.cls - thanks for reporting, and apologies for the problem!

Awesome! thanks! I did wonder if it was possible to manage recursion with just the ID? anyway, I look forward to your update!

@mickster04 if only it were as simple as using the Ids - however, the intent with recursion detection is not only to stop running if the items have been run through, but also to check if any of the items have changed prior to doing so. For Rollup's purposes, that means validating that the lookup Id and/or the value to rollup haven't changed. If they have changed, then the recursion is a valid place for rolling up to occur.
