CTBW and datasource display on rsa3

Hi gurus,

I can not see data rsa3 after ı made the neccesary transport variant configuration object datasource 1CL_OMAT001

I am not sure of choosing right class type...On the standard documents 00a type is chosen however in my case 300 is defıned and 001 is also present...Does anyone have any idea of the reason that i see 0 records on rsa3 when 0material_attr is in question...

Thanks in advance.

Edddy.
