Nagendra,

Thanks for the help. Below is the start of the batch class:

global class AccountABCMktgBatch implements Database.Batchable<sObject>, Database.Stateful{

	global Integer recordsProcessed = 0;
    global final String query;
    Last_Run_ABC_Mktg_Batch__c customSetting = Last_Run_ABC_Mktg_Batch__c.getInstance('PROD');
    //String LRDate = customSetting.LastRun_Date__c.formatGmt('yyyy-MM-dd\'T\'HH:mm:ss.SSS\'Z\'') ;
    DateTime LRDate = customSetting.LastRun_Date__c;
    
    String qry = ' SELECT id, Exempt_Mktg_ABC_Partner_Num__c, Exempt_Mktg_ABC_Region__c, '
            + 'Exempt_Mktg_ABC_Region_and_Partner_Num__c, No_of_Active_Partner_Num__c '
            + ' FROM Account '
            + ' WHERE LastModifiedDate > :LRDate';
    System.debug('query'+ qry);
    global Database.QueryLocator start(Database.BatchableContext BC){
    return Database.getQueryLocator(qry);
    }
    
    global void execute(Database.BatchableContext BC, List<account> acts){
        Set<Id> accountsToUncheck = new Set<Id>();
        Set<Id> accountsToCheck = new Set<Id>();
        List<Contact> cntsToUncheck = new List<Contact>();
        List<Contact> cntsToCheck = new List<Contact>();
        if(acts.size() > 0){
            for(Account acct: acts){
                
                if(acct.Exempt_Mktg_ABC_Partner_Num__c +  
                   acct.Exempt_Mktg_ABC_Region_and_Partner_Num__c == acct.No_of_Active_Partner_Num__c){
                       accountsToUncheck.add(acct.id);
                } else if (acct.Exempt_Mktg_ABC_Partner_Num__c + 
                           acct.Exempt_Mktg_ABC_Region_and_Partner_Num__c <> acct.No_of_Active_Partner_Num__c){
                               accountsToCheck.add(acct.id);
                           }    
            }
            
        }//End Ifs (acts.size()>0)
        if(accountsToUncheck.size() > 0){
            for(Contact cnts1 : [SELECT id, ABC_Mktg__c, No_Longer_Employed__c, Email,
                                 HasOptedOutOfEmail FROM CONTACT WHERE AccountId IN: accountsToUncheck]){
                                     if(cnts1.ABC_Mktg__c = TRUE && cnts1.id !=null){
                                         Contact cont = new Contact();
                                         cont.id = cnts1.id;
                                         cont.ABC_Mktg__c = false;
                                         cntsToUncheck.add(cont);
                                     }
                                 }
        }
        if(accountsToCheck.size()> 0){
            for(Contact cnts2 : [SELECT id, ABC_Mktg__c, No_Longer_Employed__c, Email,
                                 HasOptedOutOfEmail FROM CONTACT WHERE AccountId IN: accountsToCheck]){
                                     if(cnts2.ABC_Mktg__c = FALSE && cnts2.id != null){
                                         Contact cont2 = new Contact();
                                         cont2.id = cnts2.id;
                                         cont2.ABC_Mktg__c = TRUE;
                                         cntsToCheck.add(cont2);
                                     }
                                 }
        }
        if(cntsToUncheck.size() >0){
            update cntsToUncheck;
        }
        if(cntsToCheck.size() > 0){
            update cntsToCheck;
        }
            
    
    }
    global void finish(Database.BatchableContext BC){
        
    }
		
}

I get the following PROBLEMS in the lower section of the Developer Console:

AccountABCMktg - 13 - Expecting ')' but was: 'query'
AccountABCMktg - 13 - Unexpected token ')'.
AccountABCMktg - 13 - Invalid constructor name: System.debug


Thanks again,

Robert
