wild card in for all entries

hi,

  my issue is that,

select * from mseg into corresponding fields of table it_mseg_105 where bwart = '105'.

select * from mseg into corresponding fields of table it_mseg_103 for all entries in it_mseg_105 where matnr = it_mseg_105-matnr and bwart = '103'.

in this second select query,i have to pass wild card value as,

select * from mseg into corresponding fields of table it_mseg_103 for all entries in it_mseg_105 where matnr like it_mseg_105-matnr% and bwart = '103'.

but i cant able to fetch value.

help me out.

regards,
