Hi All,

I am using the wrapper class to achieve the desired functionality..also i am referring the following link:

http://wiki.developerforce.com/index.php/Wrapper_Class

also, i am getting the following error:

Compile Error: Invalid field con for SObject RR__c at line 46 column 27

please suggest, where am i wrong....

Hi All,

On the Proposal__c object page i have two lookup fields.. one for Resource_Requirement__c object and another for  RR__c object. while creating the new proposal as i'll select the value for Resource_Requirement__c object.. using the lookup field..i should be able to view all the RR__c records related to selected value of Resource_Requirement__c on the visualforce page.... 

public class AllRRs
{
    private Resource_Requirement__c rrdetail;
    public List<RR__c> propdetail;
       
    public AllRRs(ApexPages.StandardController controller)
    {
        rrdetail=(Resource_Requirement__c)controller.getre​cord();
        propdetail = new List<RR__c>();
        RR__c rrlist = new RR__c();
        rrlist.RRF__c = rrdetail.id;
        propdetail.add(rrlist);                        
    }
   
    public RR__c[] getCaseRecords()
    {
        RR__c[] rrdetail = [select id,name,gPAC__c,RRF__c,Long_Term_Resource_Location​__c,Priority__c,Required_Skill__c,RR_Status__c,RM_​Phase__c from RR__c where RRF__c =:rrdetail.id];
        return rrdetail;
    }
}

Hi,

I need to create the visualforce page that should display all the records based on the lookup field value selected. Please guide me.

Thanks

Hi,

I have a lookup field on RR__c and Proposal__c for another object Employee__c. Based on the field value in Proposal object i need to update the RR__c record. I am using the following code..which is throwing an error

Hi All,

Sorry to mark it urgent, as i need to implement this soon...

I have a custom object with Master detail Relationship, now i want to make this field as lookp field (reason: i may not have the master record each time for the detail record). Please let me know the way of converting the master field to Lookup, or any other Data Type.

or else, is there any way to to mark the Master Detail field as non-mandatory on the detail objects page layout

Please let me know..

Thanks

Hi,

I have a master detail relationship between Opportunity( as master) and Custom object (as detail).

I want to update all the detail records, if i change / update any detail record. I mean all the detail records should contain same value. If i am changing any record, that should get changed other detail records as well..

trigger updateallRequisitions on Opportunity (after update) {
    List < Id > OppsIds = new List < Id >();
    List < Id > RRIds = new List < Id >();
    for(Opportunity rem: Trigger.New) {    
        if(rem.test__c != 'Closed'){    
           List<RR__c> proObj = [select p.Id,p.Bill_Rate__c from RR__c p where p.Opportunity__c =:rem.Id];
           if(proObj.size() > 0){
               for(RR__c pc: proObj ){
                   pc.Bill_Rate__c = rem.test__c ;
                   update pc;
               }
           }          
        }      
    }
}

Thanks

Hi,

I have a master field that need to get updated based on all detail records.

In the detail records i have the status field, if for all the detail records value of the Status field is "Closed" then the master field value should also be closed.. (i.e. the value of the master field will be "closed" only if all detail records are "closed")

how can i achieve that...

Hi ,

I have a master object with tthe date field Test__c. And i have multiple detail records associated with the master record.

Among all the detail record i need to catch the largest date and copy it to the master field.

Please suggest how can i achieve this with the help of trigger??

Hi,

I want to convert leads to an opportunity. Please let us know how to map between the Lead's Custom Fields to Opportunities Standard fields and Lead's Standard Fields with Opportunities Custom Fields.

Thanks

Hi All,

I have Two Objects with Master Detail relationship.

I have written a trriger on the Detail object to update a field say 'Field A' of the Master object. The Same field 'Field A' is also getting updated with a Workflow on the Master Object. Now, once my workflow's condition gets satified. my field gets updated.. i am ok with that...

But the problem comes when my workflow condition gets failed.. i want the value from the Trigger should get now updated..

I mean once my workflow condition gets False.. the trigger should get fire to update that field...

The trigger on the detail object is written on After Insert, After Delete events..

I hope that i am able to explain the problem....

please suggest,..

Hi,

I have a Master object and a Detail object. In the Master object i have a Text field that is getting updated based on the child object records.

Also, the same Master field is also getting updated based on the workflow.

No, my question is if i have set a value of taht field using the workflow once my workflow condition gets dissatified my the value set by the trigger should get updated..

Please let me know how can i do this..

Hi,

Master Object > RMG_Employee_Master__c

Detail object > Proposal__c

Detail Object Field > Status__c

Under this master object, I have number of detail object records.

The functionality is something like when I create a new record in the Detail Object where Status__c is not equal to ‘Proposed’, than for all the other records [already created] Status__c should become ‘Closed’.

Please let me know is this can be achieved?? Thanks

Hi,

I need to constantly update the master field based on the detail field value i.e. a picklist field with multiple values.

Master Object > RMG_Employee_Master__c

Master Object Field > Proposal_Status__c

Child Object > Proposal__c

Child Object Field > Status__c

I am able to update the master field based on the detail field value. But how can  loop through the multiple detail records to set the value of one master field:

trigger proposalstatus on Proposal__c (after insert,after update)
{

   List<RMG_Employee_Master__c> opps = new List<RMG_Employee_Master__c>();
   List<ID> masterIds = new List<ID>();
   Map<ID, String> childDetailMap = new Map<ID, String>();
  
   for(Proposal__c c: Trigger.new)
    {
      masterIds.add(c.RMG_Employee_Code__c);
      childDetailMap.put(c.RMG_Employee_Code__c, (c.Status__c));
    }
    opps = [select id, Proposal_Status__c from RMG_Employee_Master__c where id in :masterIds];
 
   for(RMG_Employee_Master__c rem: opps)
    {
      rem.Proposal_Status__c = childDetailMap.get(rem.id);
    }
    if(opps.size() > 0)
    {
     Update opps;
     }
}

Hi All,

On the Proposal__c object page i have two lookup fields.. one for Resource_Requirement__c object and another for  RR__c object. while creating the new proposal as i'll select the value for Resource_Requirement__c object.. using the lookup field..i should be able to view all the RR__c records related to selected value of Resource_Requirement__c on the visualforce page.... 

public class AllRRs
{
    private Resource_Requirement__c rrdetail;
    public List<RR__c> propdetail;
       
    public AllRRs(ApexPages.StandardController controller)
    {
        rrdetail=(Resource_Requirement__c)controller.getre​cord();
        propdetail = new List<RR__c>();
        RR__c rrlist = new RR__c();
        rrlist.RRF__c = rrdetail.id;
        propdetail.add(rrlist);                        
    }
   
    public RR__c[] getCaseRecords()
    {
        RR__c[] rrdetail = [select id,name,gPAC__c,RRF__c,Long_Term_Resource_Location​__c,Priority__c,Required_Skill__c,RR_Status__c,RM_​Phase__c from RR__c where RRF__c =:rrdetail.id];
        return rrdetail;
    }
}

I have a lookup field on RR__c and Proposal__c for another object Employee__c. Based on the field value in Proposal object i need to update the RR__c record. I am using the following code..which is throwing an error

Too many SOQL queries: 101

trigger updateEmpinRR on Proposal__c (after insert,after update)
{

        List < Id > rrIds = new List < Id >();
        List < Id > proposalIds = new List < Id >();
        for ( Proposal__c  c: Trigger.New )
        {
            proposalIds.add( c.Id );
            rrIds.add(c.Proposal_RR__c);
        }
        List<RR__c> opps = [select id, Selected_Employee__c from RR__c where id in :rrIds];
        Map < Id ,RR__c > empmap = new Map < Id , RR__c >();
        for ( RR__c  a : opps   )
        {
            empmap.put( a.Id, a);
        }
        List < RR__c > EmpToUpdate = new List < RR__c >();
        for(Proposal__c c: Trigger.New)
        {
            RR__c ac = empmap.get( c.Proposal_RR__c);        
            if ( ac == null )
            {   
                  continue;
            }
            If (c.Status__c == 'Selected-New')
            {
               ac.Selected_Employee__c = c.RMG_Employee_Code__c;   
               EmpToUpdate.add( ac );
            }
            else
            {
              ac.Selected_Employee__c = null;   
              EmpToUpdate.add( ac );
            }
     
                     
            
                        
        }
        upsert EmpToUpdate;     
}

Hi All,

Sorry to mark it urgent, as i need to implement this soon...

I have a custom object with Master detail Relationship, now i want to make this field as lookp field (reason: i may not have the master record each time for the detail record). Please let me know the way of converting the master field to Lookup, or any other Data Type.

or else, is there any way to to mark the Master Detail field as non-mandatory on the detail objects page layout

Please let me know..

Thanks

Hi,

I have a master detail relationship between Opportunity( as master) and Custom object (as detail).

I want to update all the detail records, if i change / update any detail record. I mean all the detail records should contain same value. If i am changing any record, that should get changed other detail records as well..

trigger updateallRequisitions on Opportunity (after update) {
    List < Id > OppsIds = new List < Id >();
    List < Id > RRIds = new List < Id >();
    for(Opportunity rem: Trigger.New) {    
        if(rem.test__c != 'Closed'){    
           List<RR__c> proObj = [select p.Id,p.Bill_Rate__c from RR__c p where p.Opportunity__c =:rem.Id];
           if(proObj.size() > 0){
               for(RR__c pc: proObj ){
                   pc.Bill_Rate__c = rem.test__c ;
                   update pc;
               }
           }          
        }      
    }
}

Thanks

Hi,

I am able to create single record for the custom detail object using the VF page, how to define the number of records should get created on VF page itself, so that when i hit save button the defined number of records should get created??

my Apex Class:

public class OrderEntry 
{
    public List<RR__c> ords {get; set;}
    private final Opportunity parOrd;
    public OrderEntry(ApexPages.StandardController​ myController) {
        parOrd=(Opportunity)myController.getrecord​();
        ords = new List<RR__c>();
        RR__c LitOrd = new RR__c();
        LitOrd.Opportunity__c = parOrd.id;
        ords.add(LitOrd);}

    public void addrow() {
        RR__c LitOrd = new RR__c();
        LitOrd.Opportunity__c = parOrd.id;
        ords.add(LitOrd);}
            
    public void removerow(){
        Integer i = ords.size();
        ords.remove(i-1);}
            
    public PageReference save() {
         insert ords;
        PageReference parrec = new PageReference('​/'+ parOrd.id);
        parrec.setRedirect(true);
        return parrec; }
}

VF Page:

<apex:page standardController="Opportunity" extensions="OrderEntry">
