ALV issue

[Former Member]

Hi,

I am working on developing a report in ALV and came across an issue with the FM 'REUSE_ALV_FIELDCATALOG_MERGE'. Here is the code..

data: alv_fc type table of slis_fieldcat_alv with header line,

Data: Begin of error occurs 0,

pernr(12),

empname(40),

paystartdate(15),

payenddate(15),

amount(15),

warning(50),

End of error.

Data: error_alv like error occurs 0 with header line.

THE CODE...

error_alv has the data records that need to be displayed on ALV.

clear alv_fc[].

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

*i_program_name = sy-repid

i_internal_tabname = 'error_alv'

*i_inclname = sy-repid

CHANGING

ct_fieldcat = alv_fc[] ...........>

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3.

if sy-subrc <> 0.

message e007(hrben00listreports).

endif.

It is throwing an runtime error that the filed type is not matching between alv_fc[] and error_alv.

what am I missing here?

Any thoughts?

Thanks,

First of all the structure u pass should be DDIC structure.you should not do type ,but make structure in se11..

and define the changing parameter alv_fc of type slis_t_fieldcat_alv.

jus use:

DATA: alv_fc TYPE slis_t_fieldcat_alv.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = sy-repid

i_internal_tabname = error_tab defined in se11

CHANGING

ct_fieldcat = alv_fc.

• EXCEPTIONS

• OTHERS = 1.

hope it solves...

Thanks, I knew that but I wanted to do it without creating the strucutre and directly reading the data from the internal table to the ALV field catalog. I understood that it does not work.

Try this:

DATA: g_fieldcat_tab TYPE slis_t_fieldcat_alv,
      w_fieldcat_tab TYPE LINE OF slis_t_fieldcat_alv.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name         = sy-repid
      i_internal_tabname     = 'LT_VBAK'   " caps
      i_structure_name       = 'VBAP'   "caps
    CHANGING
      ct_fieldcat            = g_fieldcat_tab[]
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.
