Hi, I've tried to wrote the concept down .... I didn' check the syntaxt so it could be the case that some misspells are in the code ... but you will see how it works!

trigger SetContractdetailsOnContact on Opportunity (after insert, after update) { 
     // extract the contact id's fom the opportunities and store them in a list 
     List contactIDs = new List(); 
     for (Opportunity opp : trigger.new){ 
          if(opp.YOURCONTACTFIELD__c != null){ 
               contactIDs.add(opp.YOURCONTACTFIELD__c); 
           } 
     } // now query the contacts and put them in a Map 
   
     Map contactMap = new Map(); 
     for(Contact contact : [SELECT ID, ContractLength__c, ContractServiceDate__c from Contact Where id in :contactIDs]){ 
           contactMap.put(contact.id, contact); 
     } 
     // iterate over the opportunities and update the contact records 
     for(Opportunity opp : trigger.new){ 
         // only proceed if the CONTACTFIELD is not null - else skip the opportunity 
         if(opp.YOURCONTACTFIELD__c != null){ 
              // get the contact from the map 
              Contact c = contactMap.get(opp.YOURCONTACTFIELD__c); 
              // double check if the contact is really there - if not skip the record 
              if(c != null){ 
                    // check if the trigger is in the insert mode 
                    if(trigger.isInsert){ 
                            // if contractLength is set update the corresponding field on the contact record 
                            if(opp.ContractLength__c != null){ 
                                 c.ContractLength__c = opp.ContractLength__c; 
                            } 
                            // if ContractServiceDate is set update the corresponding field on the contact record 
                            if(opp.ContractServiceDate__c != null){ 
                                 c.ContractServiceDate__c = opp.ContractServiceDate__c; 
                            } 
                     }else if(trigger.isUpdate){ 
                            // if the trigger is in the context of updating oppty records 
                            // if contractLength is set AND changed update the corresponding field on the contact record 
                            if(opp.ContractLength__c != null && trigger.oldMap.get(opp.ID).ContractLength__c != opp.ContractLength__c){ 
                                  c.ContractLength__c = opp.ContractLength__c; 
                            } 
                            // if ContractServiceDate is set AND changed update the corresponding field on the contact record 
                            if(opp.ContractServiceDate__c != null && trigger.oldMap.get(opp.ID).ContractServiceDate__c != opp.ContractServiceDate__c){ 
                                  c.ContractServiceDate__c = opp.ContractServiceDate__c; 
                            } 
                      } 
               } 
         } 
     } 
     upsert contactMap.values(); 
}

[Dirk Gronert]

Will this work for you?!:

if(opp.ContractServiceDate__c != null && opp.ContractServiceDate__c < c.ContractServiceDate__c){ 
                                 c.ContractServiceDate__c = opp.ContractServiceDate__c; 
                            }

Pls help me how can solve this problem.............

[Dirk Gronert]

Sure .. The answer is easy ...

if(c.Original_Service_Start_Date__c!= null && o.CloseDate< c.Original_Service_Start_Date__c) // this code for Minimum date updated
             c.Original_Service_Start_Date__c  = o.CloseDate;
else
             c.Original_Service_Start_Date__c  = o.CloseDate;

You are setting c.Original_Service_Start_Date__c with the same value o.CloseDate in if and else ....!

Something like this would do the trick:

if(c.Original_Service_Start_Date__c!= null && o.CloseDate< c.Original_Service_Start_Date__c) // this code for Minimum date updated
             c.Original_Service_Start_Date__c  = o.CloseDate; 

Without the else ;-)

Hi Dirk Gronert this code is not working.

if(c.Original_Service_Start_Date__c!= null && o.CloseDate< c.Original_Service_Start_Date__c) // this code for Minimum date updated
             c.Original_Service_Start_Date__c  = o.CloseDate;
else
             c.Original_Service_Start_Date__c  = o.CloseDate;

You are setting c.Original_Service_Start_Date__c with the same value o.CloseDate in if and else ....!

Something like this would do the trick:

if(c.Original_Service_Start_Date__c!= null && o.CloseDate< c.Original_Service_Start_Date__c) // this code for Minimum date updated
             c.Original_Service_Start_Date__c  = o.CloseDate;

1. i created contact.

                                 i. for this contact i created one opportunity  that time i choose date field is 13/2/2012. now contact populated this date.

                              ii. for this same contact i created second opportunity that time i choose date field is 24/2/2012 . now Contact populated this date.  this happend currently

but here  minimum date is  13/2/2012  i need this date is populated in contact how can solve this problem . pls help me...............
