I need to copy Long Text Area field - Quote_Methods__c at Account Level to Opportunity Level field - Quote_Instruc__c. I know it be cannot be done by formula, and workflow/process builder is work around but I need something that changes the field data at opportunity level dynamically, when the data in Quote_Methods__c at Account level is changes. It should apply to all child records [opportunities]. I think can be done by before update trigger on Account by using try and catch error method but not that expert in coding level. Please help me with sample code/ anything. I appreciate your time and help.
