I am trying to create a test data for coverage. The field is a formula field and it has a master-detail relationship with another object, then I create a recode in the object. but how can I reference the field in the detail object? I am getting an error:
Field is not writeable
How Can I do that?
PLS_Code__c is a formula field and formulae are:
VWC_Positioner_LimitSwitch__c PLSObj = new VWC_Positioner_LimitSwitch__c(); PLSObj.Code__c = '2HPB'; PLSObj.Description__c = 'This is test data.'; insert PLSObj; VWC_PLS_Combination__c pls_Combination = new VWC_PLS_Combination__c(); pls_Combination.Price__c = 123; pls_Combination.Positioner_Limit_Switch__r.Code__c = PLSObj.id; insert pls_Combination; instance.selectedPositioner = '2HPB';`
