problem regarding alv

[Former Member]

report zalv_grid.

tables: kna1.

type-pools: slis.

data: fact type slis_t_fieldcat_alv,

i_repid like sy-repid.

data: begin of itab occurs 0,

kunnr like kna1-kunnr,

name1 like kna1-name1,

end of itab.

select-options: s_kunnr for kna1-kunnr.

select * from kna1 into corresponding fields of table itab up to 10 rows

where kunnr in s_kunnr.

call function 'reuse_alv_fieldcatalog_merge'

exporting

i_program_name = i_repid.

i_internal_tabname = 'itab'

i_inclname = i_repid

changing

ct_fieldcat = fcat.

call function 'resuse_alv_list_display'

exporting

i_callback_program = i_repid

it_fieldcat = fcat

i_save = 'a'

table

t_outtab = itab.

when i run this program it runs without any syntex errror but it gives message "fieldcatalog does not exist". how to resolve this problem plz help me i am new in ALV.

i_repid must contain the progrm name

try one of the following before the fieldcatalog_merge call:

i_repid = 'ZALV_GRID'.

i_repid = sy-repid.

You may also need to put internal table name in upper case:

i_internal_tabname = 'ITAB'

The function REUSE_ALV_FIELDCATALOG_MERGE is used for retrieve a catalog =

from a table defined in DDICT. Then you can modify it as you want. You =

can see an example in BALV* programs demos.

Look this example:

in the program J_1AINFG is called as:

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE' =20

EXPORTING =20

i_internal_tabname = TABLEINT

i_structure_name = 'J_1AIFALVHDR' =20

CHANGING =20

ct_fieldcat = i_fieldcat[]. =20

where i_structure name is defined in DDICT. Then you can add, delete, or =

modify masks, lengths, etc. properties of fields in this table.

In my program I need add a lot of fields

LOOP AT i_fieldcat INTO wa_fieldcat. =20

MOVE wa_fieldcat TO wa_auxfieldcat. =20

CASE wa_fieldcat-col_pos. =20

WHEN 27. =20

CLEAR wa_fieldcat. =20

wa_fieldcat-fieldname = 'COEFIC1'. =20

wa_fieldcat-tabname = g_tabname_header. =20

wa_fieldcat-col_pos = 27. =20

wa_fieldcat-seltext_s = 'Coef.Per.'. =20

wa_fieldcat-seltext_m = 'Coefic.Per=EDodo'. =20

wa_fieldcat-seltext_l = 'Coeficiente del Per=EDodo'. =20

wa_fieldcat-outputlen = 9. =20

wa_fieldcat-just = 'R'. =20

APPEND wa_fieldcat TO auxcatalogo. =20

ADD 1 TO wa_auxfieldcat-col_pos. =20

..

ENDCASE.

ENDLOOP.

i_fieldcat[] = auxcatalogo[].

[Former Member]

the function REUSE_ALV_FIELDCATALOG_MERGE does not require the definition of the catalog structure to be stored in the dictionary - It can just as easily use an internal table that is only defined in your program.

When you have an internal table defined with a lot of fields using this function to set up the field catalog can greatly simplify your program. As long as all fields in the internal table are defined as 'LIKE' a dictionary field they will inherit the attribute of that dictionary field. One note is that the function does not recognise fields defined as 'TYPE' except for basic types like "TYPE C". So "WERKS LIKE MARD-WERKS" will work, but "WERKS TYPE MARD-WERKS" will not.

You simply need to call the REUSE_ALV_FIELDCATALOG_MERGE function and give it your program name and the name of the structure defining your internal table - it then returns a field catalog which you can loop at to modify descriptions, widths, etc.

i made

"I_INTERNAL_TABNAME = 'ITAB'"

and

"I_SAVE = 'A'"

previously i used lower case.

thanks for solution
