Hi..,

Sy-tabix works only with in a LOOP statement.

Sy-tabix gives the currently processing record number of the internal table inside the loop. sy-index doesnot work inside the loop .. endloop.

Sy-tabix works only with the Internal table operations..

sy-tabix always give the current processing record number in a particular internal table.

Sy-index works in processing loops.

sy-index gives the current loop pass number of the corresponding loop.

Hi,

system variable to find the number of records in an internal table - sy-tabix or sy-dbcnt.

SY-TABIX means Table Index. This signifies the number of table index. Each row of a table has certain index or counter. The value of sy-tabix for the last entry would be equivalent to number of table entries.

SY-INDEX means the number of Iterations for a loop. bascially DO - ENDO .

SY-INDEX is not equal to SY-TABIX.

Check the belwo program

report tabix_index.

DO 100 times.

wa_tab-index = sy-index.

append wa_tab to itab.

clear wa_tab.

enddo.

loop at itab into wa_tab.

write:/1 sy-tabix.

endloop.

Regards,

Priyanka.

describe table itab lines N.

DESCRIBE is the statement which gives the number of records of an internal table

N returns the number of records of an internal table.

SYDBCNT will have the number of records in Itab and also u can use..

Describe table itab.

l_Var1 = sy-tfill..

This also will guive u the total records.

Sy-Tabix will have the index of the record which is coming in the itab.

Loop at itab.

SY-TABIX will have the index of the loop.

endloop.

The system variable which is used to find the no of records in internal table is sy-tfill..

describe itab .

if sy-subrc = 0.

n = sy-tfill.

endif.
