I tried to use the Salesforce to Salesforce functionality in my Apex code.for this I used two sandboxed organizations,each activated their Salesforce to Salesforce and a connection has alos been implemented.I then published a record->"CurrencyMaster" and some fields similarly on the other environment I subscribed to the same record and added it to "CurrencyMaster1" record.Now how can I access some of the values in the table"CurrencyMaster" in my other environment?

My Apex code:->

List<PartnerNetworkConnection> connMap = new List<PartnerNetworkConnection>([select Id, accountId, ConnectionStatus, ConnectionName from PartnerNetworkConnection where ConnectionStatus = 'Accepted']);
        for(PartnerNetworkConnection network : connMap) {    
        PartnerNetworkRecordConnection newrecord = new PartnerNetworkRecordConnection();

        newrecord.ConnectionId = network.Id;
        newrecord.LocalRecordId = [select id from CurrencyMaster1__c limit 1].Id;  
         //newrecord.RelatedRecords = 'Contact,Opportunity,Orders__c';
        //newrecord.SendClosedTasks = true;
        //newrecord.SendOpenTasks = true;
        //newrecord.SendEmails = true;   
            
        insert newrecord;   
        }

 Please advise.The documentation was less on the same.Where am I going wrong??
