Syntax error in the class while activating DOE DM MAS_PARTNER

Hi there, I am getting an error message while generating DOE DM MAS_PARTNER. Appreciate any help.

SDOE_WB --> Activate DM “DM_FOR_PARTNER”

Data Object “MAS_PARTNER” inconsistent

When i check the class in SE80

Any idea what went wrong during activation? All other DM's are activated successfully.

Thanks,Suhas
