Error while trying to create Generic Articles with variants using LSMW (ARTMAS05)

Hello all,

While trying to create Generic Articles master using LSMW idoc ARTMAS05, I am getting an error message 'The generic article could not be created as a class'. I am trying to create 2 variants and have filled up the corresponding characteristics segment. I am able to do it manually using MM41.

Any help appreciated.

Thanks

Anmol
