Error Method does not exist or incorrect signature

Question

Getting the following error at line number 7.

Method does not exist or incorrect signature: void add(Auto_Risk_Fill__c) from the type Map

List<Auto_Risk_Fill__c> autoValues = new List<Auto_Risk_Fill__c>(); autoValues = [SELECT Answer__c,Answer_Comments__c,Risk_Factor_Name__c,Category__c,Opportunity_BidLevel__c,Opportunity_Install_Country__c,Opportunity_Project_Scope__c,P_L__c,Risk_Module__c FROM Auto_Risk_Fill__c]; Map<String,Map<String,Auto_Risk_Fill__c>>> mapOfMaps = new Map<String,Map<String,List<Auto_Risk_Fill__c>>>(); for(Auto_Risk_Fill__c autoObj : autoValues){ if(mapOfMaps.containsKey(autoObj.P_L__c)){ //mapOfMaps.get(autoObj.Risk_Factor_Name__c).add(autoValues); System.debug('dsfds'+mapOfMaps); } else{ Map<String,Auto_Risk_Fill__c> riskItems = new Map<String,Auto_Risk_Fill__c>(); riskItems.put(autoObj.Risk_Factor_Name__c,autoObj); mapOfMaps.put(autoObj.P_L__c,riskItems); } } System.debug('hey'+mapOfMaps);

As it a “map of maps” it should be a put not an add.

you want to get Map<String,Auto_Risk_Fill__c> by autoObj.P_L__c and after that put to this Map put(autoObj.Risk_Factor_Name__c,autoObj).

Your code will look like

List<Auto_Risk_Fill__c> autoValues = [ select Answer__c, Answer_Comments__c, Risk_Factor_Name__c, Category__c, Opportunity_BidLevel__c, Opportunity_Install_Country__c, Opportunity_Project_Scope__c, P_L__c, Risk_Module__c from Auto_Risk_Fill__c ]; Map<String,Map<String,Auto_Risk_Fill__c>>> mapOfMaps = new Map<String,Map<String, Auto_Risk_Fill__c>>(); for(Auto_Risk_Fill__c autoObj : autoValues){ Map<String, Auto_Risk_Fill__c> riskItems = null; if(mapOfMaps.containsKey(autoObj.P_L__c)){ riskItems = mapOfMaps.get(autoObj.P_L__c); }else{ riskItems = new Map<String, Auto_Risk_Fill__c>(); } riskItems.put(autoObj.Risk_Factor_Name__c, autoObj); mapOfMaps.put(autoObj.P_L__c, riskItems); } System.debug('mapOfMaps:' + mapOfMaps);

Fifth line is wrong -

Map<String,Map<String,Auto_Risk_Fill__c>>> mapOfMaps = new Map<String,Map<String,List<Auto_Risk_Fill__c>>>();

Right and left side structure are not same. Make it same.
