System variable for columns in internal table

former_member384574 — Thu, 15 Mar 2012 12:54:42 GMT

Hello Experts,

Does anybody know if there's any system data for know the columns of an internal table? The variable sy-TFILL gives us the number of rows but I'm not sure if there's any other variable for find the columns....can anybody help me please?

Thanks in advance,

Regards.
Rebeca

SY-TLENG woul be the length of the lines. But I doubt for number of fields, if the records are not a flat structure, what would be the number of column of a deep structure ? Would it be a constant or would it depend on the values of each record. Nevertheless you can CL_ABAP_STRUCTDESCR's methods DESCRIB_BY_* which will return a ref to CL_ABAP_TYPEDESCR.

Raymond

Hi,

I also doubt if there is a system field that holds the number of columns in an internal table. But you can get the column count by working around. Take a look at this thread. http://scn.sap.com/thread/135452

Hi,

assign the structure to a field symbol and use assign-components ... press F1 help on assign components...

if sy-index = 1.
ASSIGN COMPONENT sy-index OF STRUCTURE <fs_record> TO <fs_comp>.
IF sy-subrc <> 0.
count = count + 1.
ENDIF.
endif.

Otherwise use the below code,

DO.

ASSIGN COMPONENT SY-INDEX OF STRUCTURE GWA_ITAB TO <FS>.

IF SY-SUBRC = 0.

CONTINUE.

ELSE.

G_COLNUMBER = SY-INDEX.

EXIT.

ENDIF.

ENDDO.

Now G_COLNUMBER - 1 , will be the no of column.

Arun

Hi,

Using Type polls Slis you can get index of the internal table..

WHEN '&IC1'.

READ TABLE <T_itpac> ASSIGNING <W_itpac> INDEX selfield-tabindex.

Hi,

I do not think there is a system field to handle this. You can read the reply from Raymond for more details.

Compared to the other solutions suggested, I would like to add the simplest way to get it.

data:lwa_structure type ty,
wa_ltype type c,
 itab type table of ty.
DESCRIBE FIELD lwa_structure TYPE  wf_ltype COMPONENTS wi_count.
Write wi_count
