Hi Kiran
I confused as you said to do SMT Mapping. As per me MDG-F is Flex mode and no SMT mapping is required in case of Flex mode,Correct?
Actually after generate srtucture step and extention of UI, For already existing fiel\d in ECC MDG extention as then it is in std IDOC segement but in case of custom field we need to add in segment as well, correct?
