ALV List: extended field isn't filled

Question

Hi experts,
I've made a alvlist and need one more field, all is working for the ALV-control but the additional field isn't filled with the values from GT_STXL_EXT (in debugger I can see the values)! I already searched in forum and looked into the ALV Grid Control reference but with no success to solve this problem.

TYPE-POOLS: slis.

         INCLUDE STRUCTURE stxl.

Answer 1

try this it may work
ls_fcat-fieldname = 'TDLINE'. " IN CAPS
*ls_fcat-ref_table = 'STXITFD'.
ls_fcat-ref_table = 'GT_stxl_ext'.
ls_fcat-ref_field = 'tdline'.
ls_fcat-inttype   = 'C'.
ls_fcat-outputlen = '132' .
  ls_fcat-coltext   = 'Materiallangtext'.
ls_fcat-seltext   = 'Materiallangtext'.
ls_fcat-datatype  = 'CHAR'.
ls_fcat-domname   = 'TDSTXLLINE'.
  ls_fcat-col_pos   = '7'.
  ls_fcat-tabname   = 'GS_STXL_EXT'.
  APPEND ls_fcat to lt_fieldcatalog.
