Accessing OpportunityLineItem ProductCode field

Question

Currently I'm having issue saving my code:

public static void myMethodMyMethod(Map<Id,OpportunityLineItem> OLIs, String action){

        for(OpportunityLineItem oli:OLIs.values()){
            system.debug('oli.ProductCode '  + oli.ProductCode);
        }

}

I keep getting this error: Invalid field ProductCode for SObject OpportunityLineItem

I was able to print out other fields information from sObject oli (i.e. OpportunityId, UnitPrice, etc). For some reason ProductCode does not work...

Any advice?

Thank you, Eric

Answer 1

1) Check your API version of the class

2) Can you try oli.product2.productcode.

As per docs

https://www.salesforce.com/us/developer/docs/api/Content/sforce_api_objects_opportunitylineitem.htm

ProductCode :This read-only field is available in API version 30.0 and later. It references the value in the ProductCode field of the related Product2 record
