Object not in the cube

Can someone tell me how do we deal with objects which are there in BW System but do not belong to the standard info cube / infosource / datasource that I am looing at . Eg:

0DISTR_CHAN : But I need this in 0IC_C03 and it is not a part of the cube / info source / datasource. And it is there in R/3 : Table : VBAK, Field : VTWEG

Thanks
