*data definition

tables:
marav. "Table MARA and table MAKT

*---------------------------------------------------------------------*
* Data to be displayed in ALV
* Using the following syntax, REUSE_ALV_FIELDCATALOG_MERGE can auto-
* matically determine the fieldstructure from this source program

Data:
begin of imat occurs 100,
matnr like marav-matnr, "Material number
maktx like marav-maktx, "Material short text
matkl like marav-matkl, "Material group (so you can test to make
" intermediate sums)
ntgew like marav-ntgew, "Net weight, numeric field (so you can test to
"make sums)
gewei like marav-gewei, "weight unit (just to be complete)
end of imat.

*---------------------------------------------------------------------*
* Other data needed
* field to store report name
data i_repid like sy-repid.
* field to check table length
data i_lines like sy-tabix.

*---------------------------------------------------------------------*
* Data for ALV display
TYPE-POOLS: SLIS.
data int_fcat type SLIS_T_FIELDCAT_ALV.

*---------------------------------------------------------------------*
select-options:
s_matnr for marav-matnr matchcode object MAT1.

*---------------------------------------------------------------------*
start-of-selection.

* read data into table imat
select * from marav
into corresponding fields of table imat
where
matnr in s_matnr.

* Check if material was found
clear i_lines.
describe table imat lines i_lines.
if i_lines lt 1.
* Using hardcoded write here for easy upload
write: /
'No materials found.'.
exit.
endif.

end-of-selection.
*---------------------------------------------------------------------*
*
* Now, we start with ALV
*
*---------------------------------------------------------------------*
*
*
* To use ALV, we need a DDIC-structure or a thing called Fieldcatalogue.
* The fieldcatalouge can be generated by FUNCTION
* 'REUSE_ALV_FIELDCATALOG_MERGE' from an internal table from any
* report source, including this report.
* The only problem one might have is that the report and table names
* need to be in capital letters. (I had it :-( )
*
*
*---------------------------------------------------------------------*

* Store report name
i_repid = sy-repid.

* Create Fieldcatalogue from internal table
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
I_PROGRAM_NAME = i_repid
I_INTERNAL_TABNAME = 'IMAT' "capital letters!
I_INCLNAME = i_repid
CHANGING
CT_FIELDCAT = int_fcat
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3.

*explanations:

* I_PROGRAM_NAME is the program which calls this function
*
* I_INTERNAL_TABNAME is the name of the internal table which you want
* to display in ALV
*
* I_INCLNAME is the ABAP-source where the internal table is defined
* (DATA....)
* CT_FIELDCAT contains the Fieldcatalouge that we need later for
* ALV display


IF SY-SUBRC <> 0.
write: /
'Returncode',
sy-subrc,
'from FUNCTION REUSE_ALV_FIELDCATALOG_MERGE'.
ENDIF.

*This was the fieldcatlogue
*---------------------------------------------------------------------*
*
* And now, we are ready to display our list

* Call for ALV list display
CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'
EXPORTING
* I_CALLBACK_PROGRAM = 'Z_ALV_SIMPLE_EXAMPLE_WITH_ITAB'
I_CALLBACK_PROGRAM = i_repid
IT_FIELDCAT = int_fcat
I_SAVE = 'A'
TABLES
T_OUTTAB = imat
EXCEPTIONS
PROGRAM_ERROR = 1
OTHERS = 2.
*
*explanations:

* I_CALLBACK_PROGRAM is the program which calls this function
*
* IT_FIELDCAT (just made by REUSE_ALV_FIELDCATALOG_MERGE) contains
* now the data definition needed for display
*
* I_SAVE allows the user to save his own layouts
*
* T_OUTTAB contains the data to be displayed in ALV


IF SY-SUBRC <> 0.
write: /
'Returncode',
sy-subrc,
'from FUNCTION REUSE_ALV_LIST_DISPLAY'.
ENDIF.
