Currency conversion error

Hi Experts,

I have configured currency conversion in BPC 7.5 NW, while running data manager package currency conversion, I am getting following error message kindly guide.

*u201CAn exception with the type CX_SY_CREATE_DATA_ERROR occurred, but was neither handled locally, nor declared in a RAISING clause*

*The data object could not be created: The type /B28/MGKDMM0G does not exist.*
