Need help on trigger logic

Hi All,

I have a requirement like child Part number update to Parent object field with comma separeted.

But issue is when status is approved then i have populated Parent id to child data with some creteria.when updating part number using before update part number is not populated in parent object  because child data is not adding before commit.

When using after update getting record is read only.

Here is code.

public  void updatePartNumber1(List<Account> rwlist){

        if(isCheck == true){

        String concatenateString = '';

        

         List<Contact> erplst = [SELECT Name,Part_Number__c,Device__r.Type__c,Device__r.Name   FROM Contact where account__c =:rwlist];

        String partnumber;

        for(Account  rw : rwlist){

            

           partnumber ='';

            system.debug('erplst'+erplst.size());

            if(rw.status__c == 'Approved' ){

            for(Contact erp : erplst){ 

               

                If(rw.Apply_RWA_All_Base_Device__c == 'Yes' && rw.Expose_RWA_to_Customer__c == 'Yes' ){

                    concatenateString += String.isBlank(concatenateString) ? erp.Part_Number__c : ',' + erp.Part_Number__c;

                    

                    if(erp.Device__r.Tapeout_Type__c  == 'Single Value'){

                        

                        partnumber = erp.Device__r.Name;

                        rw.Single_Product__c = true;

                    } 

                }else{

                    If(rw.Apply_RWA_All_Product_family__c == 'Yes' && rw.Expose_RWA_to_Customer__c == 'Yes' ){

                        concatenateString += String.isBlank(concatenateString) ? erp.Part_Number__c : ',' + erp.Part_Number__c; 

                        system.debug('concatenateString'+concatenateString);

                        

                    }

                }

                

            }

            rw.Initial_Part_Number_s_Covered__c = concatenateString;

            

            if( rw.Description_and_Part_Number__c != null && (rw.Description_and_Part_Number__c.contains(partnumber))){

                rw.Description_and_Part_Number__c = rw.Description_and_Part_Number__c;

            }else if(rw.Description_and_Part_Number__c == '' || rw.Description_and_Part_Number__c == null ){                

                rw.Description_and_Part_Number__c = partnumber;

            }else{

                 rw.Description_and_Part_Number__c = partnumber+ rw.Description_and_Part_Number__c;

            }

            

            rw.Customer_Product_Family_Name__c = true;

            rwlist.add(rw);

            }   

        }

        try{

            update rwlist;

        }catch(exception e){

            system.debug(e);

        }

        }

    }

    HI Suraj,

    Thanks for response

    I have used already same one but not working. Here problem is child data adding to parent is after update. 

    when parent status change to Approved then we are populating parent id to all child records based on creteria.

    Regards,

    Raju
