I'm facing this issue despite the fact that , I have uncheck the option "Strictly enforce picklist values" on the dependent field. Following is the  code which throws this error in PRODUCTION Org , however the passes the testing in SANDBOX :
@istest(SeeAllData=true)  private class TestEmailAlertsForQoute {             static testmethod void test() {                            Test.startTest();             Account acc = new Account(name='acc1');           insert acc;                   Opportunity oppr = new Opportunity();           oppr.AccountId = acc.ID;           oppr.Annual_Contract_Value_ACV__c = 111;           oppr.BU__c = 'MJ';           oppr.CloseDate = Date.today();           oppr.Contract_Opportunity_Estimate_CoE__c = 111;           oppr.Total_Contract_Value_TCV__c = 111;            oppr.Name = 'SubmitforQuoteApproval';            oppr.StageName = 'Prospecting';             oppr.Date_on_Opportunity_Prospecting_Stage__c = Date.today();           insert oppr;                      oppr.Region__c ='North';           oppr.Responsible_Sales_Rep__c ='Siddharth Bhatia';           update oppr;                                         Quote quot1 = new Quote ();           quot1.Name = 'TestPropForSandbox2016-10';            quot1.Status ='Draft';           quot1.OpportunityId = oppr.id ;           insert quot1;                                  quot1.Status = 'Acceptance by Client';            update quot1 ;                       Test.stopTest();          }           }

Any help resolving the error : System.DmlException: Update failed. First exception on row 0 with id 0066F00000jPi87QAC; first error: INVALID_OR_NULL_FOR_RESTRICTED_PICKLIST, bad value for restricted picklist field: Siddharth Bhatia: [Responsible_Sales_Rep__c]
