trigger quotetax on Quote (after update) {
set<id> ids=new set<id>();
for(quote q:trigger.new){
ids.add(q.id);
}
map<id,quote> oldquote=new map<id,quote>();
for(quote qold:trigger.old){
oldquote.put(qold.id,qold);
}
map<id,list<quotelineitem>> qlimap=new map<id,list<quotelineitem>>();
list<quotelineitem> qli=[select id,abc__c,quoteid from quotelineitem where quoteid=:ids];
for(quotelineitem qli2:qli){
qlimap.put(qli2.quoteid,qli);
}
system.debug('qlimap size = '+qlimap.size());
system.debug('qlimap CONTENTS = '+qlimap);
list<quotelineitem> qli4=new list<quotelineitem>();
for(quote q2:trigger.new){
quote b=oldquote.get(q2.id);
decimal c=b.tax;
if(q2.Tax!=c){
system.debug('Tax value Changed');
list<quotelineitem> qli3=qlimap.get(q2.Id);
for(quotelineitem qli5:qli3){
qli5.abc__c=true;
qli4.add(qli5);
}
}
else{
system.debug('Tax value NOT changed');
}
}
system.debug('size of quote line items = '+qli4.size());
update qli4;
}

IN Parent I have the fields city__c,Street__c,tax__c may i know where can i include city-_c,Street__c..could you update your trigger.
if(q2.Tax!=c || q2.city__c!=b.city__c || q2.street__c!=b.street__c). Hope this helps
