Hi
When we are enhancing the services provided by SAP, there are two options
1. Go to ESR start making required changes for enhancement and then generate proxy.
2. With 731, there is also an option called as MDR, where-in SPROXY transaction i can directly create Data type enhancements.
Then we need to import the WSDL into the ESR.
Could you please explain what adv/disadv and preferred option for enhancing (TM services).
