We need an extension for IDOC ARTMAS05 for article master to put customer fields, I try create extension ZARTMASX with WE30, but always get error message 'Action is not possilbe for generated idoctyps', I think, because Idoc type ARTMAS05 has been release in system, so I try Cancel Release in WE30 firstly, but get error message 'The release of the basis type cannot be reset'.
So would should I do?!
