All, I woul appreciate any help with my requirement below . I am kind of new in coding and I would appreciate any assitanceREQUIREMENT When Opportunity record is connected to one or more Matter__c record, Sum all currency values in the Total_Fees__c currency field and add Sum total value in the Engagement_Total_Fees__c field in the related Opportunity record OBJECTSOpportunity (parent object)Matter__c (Child object) custom object. OPPORTUNITY FIELDEngagement_Total_Fees__c - currency (16,2) custom field MATTER__C field Total_Fees__c - currency (16,2) custom fieldDeal__c - Lookup(Opportunity) custom field WHAT I HAD DONE Below is a trigger I created based on website https://github.com/abhinavguptas/Salesforce-Lookup-Rollup-Summaries . I am requesting if you can review my code because I received the error below “Error: Compile Error: Invalid type: LREngine.Context at line 26 column 33” The data on line 26 is “LREngine.Context ctx = new LREngine.Context(Opportunity.SobjectType, // parent object”Trigger Below/* Updated version on 17 June 16*/trigger OppRollupOnEngagement on Matter__c (after insert, after update, after delete, after undelete) // modified objects whose parent records should be updated {Matter__c[] objects = null;if (Trigger.isDelete) { objects = Trigger.old; /* Handle any filtering required, specially on Trigger.isUpdate event. If the rolled up fields are not changed, then please make sure you skip the rollup operation. We are not adding that for sake of similicity of this illustration. */ objects = Trigger.new; }/* First step is to create a context for LREngine, by specifying parent and child objects and lookup relationship field name*/ LREngine.Context ctx = new LREngine.Context(Opportunity.SobjectType, // parent object Matter__c.SobjectType, // child object Schema.SObjectType.Matter__c.fields.Deal__c // relationship field name ); /* Next, one can add multiple rollup fields on the above relationship. Here specify 1. The field to aggregate in child object 2. The field to which aggregated value will be saved in master/parent object 3. The aggregate operation to be done i.e. SUM, AVG, COUNT, MIN/MAX*/ctx.add( new LREngine.RollupSummaryField( Schema.SObjectType.Opportunity.fields.Engagement_Total_Fees__c, Schema.SObjectType.Matter__c.fields.Total_Fees__c, LREngine.RollupOperation.Sum )); /* Calling rollup method returns in memory master objects with aggregated values in them. Please note these master records are not persisted back, so that client gets a chance to post process them after rollup*/ Sobject[] masters = LREngine.rollUp(ctx, objects); // Persiste the changes in master update masters;}I would appreciate the help .
