Hi Bill,
I am posting a purchase order. On failure I should get error message of Type E from ETReturns with message. On success I should get imformation message of type I and success message. This success message , I can able to print in logs , but not getting populated in the object property.This has to be populated to the ZZMsg field which is a custom field in the same object which I am posting/ trying to post. For this I have created my own object by extending purchase order, added custom field ZZMsg.
