ALV grid display

abdulazeez12 · ‎2008 Feb 26

Hii everybody-

I do have a query on ALV grid display..

I am able to display the ALV grid perfectly alright. The problem is that I am asked to put a LOV (drop down ) on one particular field in the alv output..which I think is not possible if we use the fieldcatalog of type SLIS_T_FIELDCATALOG_ALV..instead I could see one field F4AVAILABL in fieldcatalog of type LVC_T_FCAT...

My question is can we use fieldcat of type LVC_T_FCAT and do the programming without OOPS? I thought LVC_T_FCAT is used only when we go for OOPS programming?

Can anyone help me in suggesting how to put drop down on one of the fields in ALV grid display and still use normal ABAP programming??

Thanks in advance

Shakir

TABLES AND DATA DECLARATION.

*TABLES: mara,makt.",marc.

data syrepid like sy-repid.

data sydatum(10). " LIKE sy-datum.

data sypagno(3) type n.

WHEN USING MORE THAN ONE TABLE IN ALV WE NEEED TO DECLARE THE TYPE
GROUP (TYPE-POOLS--------->SLIS)

type-pools : slis.

INTERNAL TABLE DECLARATION.

INTERNAL TABLE TO HOLD THE VALUES FROM THE MARA TABLE

data: begin of t_mara occurs 0,

matnr like mara-matnr,

meins like mara-meins,

mtart like mara-mtart,

matkl like mara-matkl,

end of t_mara.

INTERNAL TABLE TO HOLD THE CONTENTS FROM THE EKKO TABLE

data : begin of t_marc occurs 0,

matnr like mara-matnr,

werks like marc-werks,

minbe like marc-minbe.

data: end of t_marc.

INTERNAL TABLE TO HOLD THE VALUES FROM MAKT TABLE.

data : begin of t_makt occurs 0,

matnr like mara-matnr,

maktx like makt-maktx,

spras like makt-spras,

end of t_makt.

INTERNAL TABLE WHICH ACTUALLY MERGES ALL THE OTHER INTERNAL TABLES.

data: begin of itab1 occurs 0,

matnr like mara-matnr,

meins like mara-meins,

maktx like makt-maktx,

spras like makt-spras,

werks like marc-werks,

minbe like marc-minbe,

end of itab1.

THE FOLLOWING DECLARATION IS USED FOR DEFINING THE FIELDCAT
AND THE LAYOUT FOR THE ALV.
HERE AS slis_t_fieldcat_alv IS A INTERNAL TABLE WITHOUT A HEADER LINE
WE EXPLICITELY DEFINE AN INTERNAL TABLE OF THE SAME STRUCTURE AS THAT
OF slis_t_fieldcat_alv BUT WITH A HEADER LINE IN THE DEFINITION.
THIS IS DONE TO MAKE THE CODE SIMPLER.
OTHERWISE WE MAY HAVE TO DEFINE THE STRUCTURE AS IN THE NORMAL SAP
PROGRAMS.
IN THE FIELDCATALOG TABLE WE ACTUALLY PASS THE FIELDS FROM ONE OR
MORE TABLES AND CREATE A STRUCTURE
IN THE LAYOUT STRUCTURE WE BASICALLY DEFINE THE FORMATTING OPTIONS
LIKE DISPLAY IN THE ZEBRA PATTERN ,THE HOTSPOT OPTIONS ETC.

data: fieldcatalog type slis_t_fieldcat_alv with header line,

fieldlayout type slis_layout_alv.

DECLARING THE EVENTTABLE INTERNL TABLE FOR USING EVENTS LIKE
TOP-OF-PAGE ETC.

data : eventstab type slis_t_event with header line.

DECLARING AN INTERNAL TABLE TO HOLD THE DATA FOR THE TOP-OF-PAGE

data : heading type slis_t_listheader with header line.

data : heading1 type slis_t_listheader with header line.

data : heading2 type slis_t_listheader with header line.

data : heading3 type slis_t_listheader with header line.

data : heading4 type slis_t_listheader with header line.

data : heading5 type slis_t_listheader with header line.

data : heading6 type slis_t_listheader with header line.

data : heading7 type slis_t_listheader with header line.

data : heading8 type slis_t_listheader with header line.

STRUCTURE TO PASS THE COLOR ATTRIBUTES FOR DISPLAY.

data : colorstruct type slis_coltypes.
