ALV Field Catalog problem

Former Member — Tue, 02 Sep 2008 12:46:59 GMT

Hello,

I have created a field catalogue using FM REUSE_ALV_FIELDCATALOG_MERGE. Field catalog gets generated but all the fields are not present in this. Can anyone tell me, why is this happening?

Here is my Delartion and Code.

Use the function module like below it works...

DATA : incl_name LIKE trdir-name VALUE '(Your program name )'.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = sy-repid

i_internal_tabname = 'I_SET_MSEG_TEMP'

i_inclname = incl_name

CHANGING

ct_fieldcat = i_fldcat[]

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3.

Thanks,

Check by including

i_inclname = sy-repid

in Export parameters...

Tried the provided solution but did not work.

Re: ALV Field Catalog problem

Former Member — Tue, 02 Sep 2008 13:17:27 GMT

It works for me ...

Why dont give us the exact error your getting...

Try changing the itab with occurs 0

like below this might workout

BEGIN OF i_set_mseg_temp OCCURS 0,

Thanks,

I changed to to occurs 0 as well. Didnt work.

Exact problem being : I have approx 25 fields in my internal table(I_SET_MSEG_TEMP ) of which I have to fill in field catalalog. When I use FM REUSE_ALV_FIELDCATALOG_MERGE, only 5 fields are filled in field catalog. These five field are marked in bold,

kostl like csks-kostl,

ltext like cskt-ltext,

extsrvno like esll-extsrvno,

sites like setleaf-setname,

proj(5) type c,

phase(2) type c,

sgtxt like mseg-sgtxt,

sakto like mseg-sakto,

dmbtr like mseg-dmbtr,

menge like mseg-menge,

year(4) type c,

extrow like esll-extrow,

bsart like ekko-bsart,

posid like prps-posid,

packno like essr-packno,

budat like essr-budat,

sub_packno like esll-sub_packno,

userf2_num like esll-userf2_num,

peinh like esll-peinh,

gjahr like rseg-gjahr,

rshkzg like rseg-shkzg,

wrbtr like rseg-wrbtr,

swrbtr like rseg-wrbtr,

avg_price like rseg-wrbtr,

savg_price like rseg-wrbtr,

END OF i_set_mseg_temp.

I am not able to understand why other fields are not filled in field catalog.

hi,

try this change and check it

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = sy-cprog i_internal_tabname = 'I_SET_MSEG_TEMP'

i_inclname = sy-cprog

CHANGING

Hi there

Why don't you let the system do all the hard work using the RTTI (run time Information facility)



data   gv_rtti_struc type ref to cl_abap_structdescr .
data:  zog    like line of gv_rtti_struc->components .
data:  zogt   like table of zog,
data:  dref               type ref to data.

* field catalogs for the display
wa_it_fldcat       type lvc_s_fcat,
it_fldcat          type lvc_t_fcat,

create data dref type 'YOUR STRUCTURE'    can be any structure you like
 assign dref->* to <fs>.
 gv_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <fs> ).

* get the structure details into a table.
* table zogt[] contains the structure details
* From which you can  can build your  field catalog

  zogt[]  = gv_rtti_struc->components.
  loop at zogt into zog.
    clear wa_it_fldcat.
    wa_it_fldcat-fieldname = zog-name .
    wa_it_fldcat-datatype = zog-type_kind.
    wa_it_fldcat-inttype = zog-type_kind.
    wa_it_fldcat-intlen = zog-length.
    wa_it_fldcat-decimals = zog-decimals.
    wa_it_fldcat-coltext = zog-name.
    wa_it_fldcat-lowercase = 'X'.
    append wa_it_fldcat to it_fldcat.
  endloop.
*

An extra advantage of doing it this way is that the number of lines in the table ZOGT is the number of elements in your structure which can be useful for manipulating parts of the structure at run time.

This method works for ANY structure so you could build a class to use in any program

call method go_fldcat->create_fld_cat

exporting

your_struct = <fs1>

changing

fld_cat = it_fldcat.

cheers
