Hi Gaurav,
I think you are updating your triggered records directly in after trigger.
for ex:
for(Sobjecttype obj: trigger.new){obj.fieldApiName__c='Updated value';
update obj;
}
You cannot do this in After trigger as Trigger.new is read only. To update it you need to query the records from the sObject which are having their ids in trigger.new.
Hope it helps
Thanks.
