2 Sales_order  (here in Quote is looup)
3 Sales_order_line_item (here Quote is lookup and Salesorder is master)

in Sales_order_line_item object there is one field name  Import_Lending_Price__c that i want to display on Quote Object .in Quote Object  Filed i have created Lending_Price__c  this price should Sales_order_line_item object Import_Lending_Price__c 


Please check my trigger and tell me is it correct or not


trigger ParentQuoteupdate on Sales_Order_Line_Item__c (after insert, after update,before insert) {

  

Map<ID, Quote> parentQuote = new Map<ID, Quote>(); 

List<Id> listIds = new List<Id>();

  for (Sales_Order_Line_Item__c childObj : Trigger.new) 
  {
    listIds.add(childObj.Quote);
  }
  
  parentQuote = new Map<Id, Quote> ([SELECT ID,(SELECT ID,Quote__c,Import_Landing_Price__c FROM Sales_Order_Line_Item__r) FROM Quote WHERE ID IN :listIds]);
  
  for (Sales_Order_Line_Item__c  SOLI: Trigger:new){
     Quote myParentQuote = parentQuote.get(SOLI.Quote__c);
     myParentQuote.Landing_Price__c = SOLI.Import_Landing_Price__c ;
  }
  
  
  update parentQuote.values(); 


}


Error:- I am getting
Error: Compile Error: Didn't understand relationship 'Sales_Order_Line_Item__r' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names. at line 14 column 37

Please help me 

Thanks in advance

Hi Amit,

Make this (listIds) as a set of ids. and change the query like below:

parentQuote = new Map<Id, Quote> ([SELECT ID, Name,  Landing_Price__c FROM Quote WHERE ID IN :listIds]);

Mahesh

Please use below code:

Trigger ParentQuoteupdate on Sales_Order_Line_Item__c (after insert, after update) {

    Map<ID, Quote> parentQuoteMap = new Map<ID, Quote>(); 
    Set<Id> quoteIdSet = new Set<Id>();

    for (Sales_Order_Line_Item__c soli : Trigger.new) {
        quoteIdSet.add(sol.Quote__c);
    }
  
    parentQuoteMap = new Map<Id, Quote> ([SELECT ID, Landing_Price__c FROM Quote WHERE ID IN :quoteIdSet]);
  
    for (Sales_Order_Line_Item__c  soli: Trigger:new){
        Quote myParentQuote = parentQuote.get(soli.Quote__c);
        myParentQuote.Landing_Price__c = soli.Import_Landing_Price__c ;
