Standard gateway enhancement: Using DPC or DPC_EXT and MPC or MPC_EXT classes
I went through some blogs/links on enhancing Standard Gateway Service and i find them to be not clear. Few people mentioned about enhancement required in MPC for model and few told about MPC_EXT. Same applies for Data classes as well.
Can someone please point me about, difference between Base and Extension classes and also right blog/link to be followed while enhancing Standard Gateway ?
Thanks and Regards,
