NIM 0042-267

Problem :
warning: 0042-267 c_mk_lpp_source: The defined lpp_source does not have the
        "simages" attribute because one or more of the following
        packages are missing:
                ifor_ls.base
                lum.base

Solution :
It could be that your NIM master is at a lower level than the lpp_source and could not account for the two filesets: ifor_ls.base and lum.base.
