before update trigger on opportunity is not working

I have written before update trigger on opportunity but it is not working for below code, not providing error when changing stage to verbal agreement.

Note: I have created one opportunity stage as verbal agreement(80%).

for(Opportunity opp:[Select id,name, Legal_Entity_Name__r.SAP_CODE__c,StageName from opportunity where (StageName='Verbal Agreement' and id in:trigger.new)]){
        if(opp.Legal_Entity_Name__r.SAP_CODE__c==null && opp.Legal_Entity_Name__r.Name==null){
            opp.addError('Oppotunity cannot move to 80% as SAP CODE or LE is not present');

For below code there is error occured as mentioned in code but error is getting for all the stages instead of verbal agreement.

trigger SAP_CODE on Opportunity (before Update) {
    
    Set<Opportunity> updatedoppty = new Set<Opportunity>();
    for (Opportunity opp: trigger.new){
        updatedoppty.add(opp);
    }  
    
    Map<id,Opportunity> mapopty = new Map<id,Opportunity>();
    mapopty.putAll([Select id, name, Legal_Entity_Name__r.SAP_CODE__c,StageName from opportunity where (StageName='Verbal Agreement' and id in:updatedoppty)]);
    
    For (Opportunity opp: trigger.new){
        
        if(null==mapopty.get(opp.Legal_Entity_Name__r.name)){
             opp.addError('Oppotunity cannot move to 80% as LE is not present');
        }
        if(null==mapopty.get(opp.Legal_Entity_Name__r.SAP_CODE__c))
        {
               opp.addError('Oppotunity cannot move to 80% as SAP CODE is not present');
        }
    }

I guess your addError is not working because you are iterating over List<SObject> after querying using SOQL.AddError will only work if you are iterating over Trigger.New instead of using SOQL query.

Hi amol, I didn't get what u wants to convey, will you please help with changes in code.

You can use below code snippet : 
for(Opportunity opp:trigger.new){
        if(opp.Legal_Entity_Name__r.SAP_CODE__c==null && opp.Legal_Entity_Name__r.Name==null && opp.StageName='Verbal Agreement'){
		
            opp.addError('Oppotunity cannot move to 80% as SAP CODE or LE is not present');
}
}

instead of your first code snippet because here you are iterating over SOQL query thats why it's not working 
for(Opportunity opp:[Select id,name, Legal_Entity_Name__r.SAP_CODE__c,StageName from opportunity where (StageName='Verbal Agreement' and id in:trigger.new)]){
        if(opp.Legal_Entity_Name__r.SAP_CODE__c==null && opp.Legal_Entity_Name__r.Name==null){
            opp.addError('Oppotunity cannot move to 80% as SAP CODE or LE is not present');

trigger Oppty on Opportunity (before update) {
    for(Opportunity opp:Trigger.New){
        if(opp.StageName =='Verbal Agreement'){
            System.debug('Inside Trigger---->');
            opp.addError('Oppotunity cannot move to 80% as SAP CODE or LE is not present');
        }
  
}
}

Please check below trigger, 
  
trigger SAP_CODE on Opportunity (before Update) {
   for(Opportunity opp:trigger.new){
           
        if(opp.StageName=='Verbal Agreement'){
            System.debug('Stage is verbal');
            
            if(opp.Legal_Entity_Name__r.Name==null){
                System.debug('inside entity name');
                opp.addError('Oppotunity cannot move to 80% as LE is not present');
                
                 If(opp.Legal_Entity_Name__r.SAP_CODE__c==null){
                    opp.addError('Oppotunity cannot move to 80% as SAPE CODE is not present');
                    System.debug('SAP code not available');
                }
            }
            else{
            system.debug('SAP code is available');
            }
        }
    }
}

Trying to run trigger with below code:
  
Opportunity opp= new Opportunity(name='demo', stagename='Qualification', closedate=system.today());
Account demoacc=[Select id from Account where name='Demo Account'];
opp.accountid=demoacc.id;
insert opp;
System.debug('opp inserted');
opp.stagename='verbal agreement';
try{
update opp;
}catch(Exception e)
{e.getmessage();}
Legal_Entity__c LEDemo = new Legal_Entity__c();
insert LEDemo;
opp.Legal_Entity_Name__c=LEDemo.id;
System.debug('LE inserted');
try{
update opp;
}catch(Exception e)
{e.getmessage();}
LEDemo.SAP_CODE__c='0008';
system.debug('SAP CODE updated');
try{
update opp;
}catch(Exception e)
{e.getmessage();}
Output:

I am not able to call Legal Entity object's field(providing null values) so the code is getting failed.
Please suggest how to call.
