REUSE_ALV_FIELDCATALOG_MERGE takes not all the fields

Question

I have a problem with REUSE_ALV_FIELDCATALOG_MERGE FM. I need to add 5 fields into ALV.

DATA: BEGIN OF gt_collective7 OCCURS 0,
    selected(1),
    dat LIKE resb-bdter,
    overdue TYPE c,
    werks   LIKE resb-werks,
    extwg   LIKE mara-extwg,
    vd      LIKE fmfincode-fincode,
 ...
      TM like afvc-tplnr,
      ARBPL_Z like pat106-entries,
      ARBPL_R like pat106-entries,
      PLTXT like iflo-pltxt,
      lgort like resb-lgort,
  END OF gt_collective7,

gt_collective7 defined. Next i use

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name         = sy-repid
      i_internal_tabname     = 'GT_COLLECTIVE7'
      i_inclname             = sy-repid
      i_bypassing_buffer     = 'X'
    CHANGING
      ct_fieldcat            = fieldcat
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.

and inside fieldcat there's no new fields appear. What could be a problem in this case? I thought that it could be 'type' inside gt_collective7 definition, but no - it worked just fine previously.

不知道它到底有什么帮助，但是以小写形式声明了gt_collective7的所有其他字段，并以某种方式重新激活了程序，从而解决了问题。
