Hi,

This can be done in several ways. But the latest and simple way is as follows.

DATA : BEGIN OF str_test,

n1 TYPE i,

n2 TYPE i,

END OF str_test.

DATA : itab LIKE STANDARD TABLE OF str_test WITH HEADER LINE.

DO 10 TIMES.

CLEAR str_test.

str_test-n1 = sy-index.

str_test-n2 = sy-index * 2.

APPEND str_test TO itab.

ENDDO.

IF LINES( itab ) ne 0.

LOOP AT itab.

WRITE 😕 itab-n1, itab-n2.

ENDLOOP.

ENDIF.

Simple code is : Lines(<table name>) gives number of lines in internal table.

All the very best to you.

Hi Ravi,

Just include the field SY-TABIX in your Write statement for the internal table. This should help you in achieving the no. of records.

Reward points if useful,

by using sy-dbcnt we can find the total number of records in the internal table.

hi,

report zsample.

tables:mara.

data:itab like mara occurs 0 with header line.

data:v_lines type i.

select-options :s_matnr for mara-matnr.

start-of-selection.

select * from mara into table itab where matnr in s_matnr.

clear v_lines.

if sy-subrc = 0.

describe table itab lines v_lines.

write: v_lines , 'No of records in internal table for the given range'.

endif.

Hi ,

Internal table in ABAP

*An internal table is a run time instance. It get created when program starts execution.

*It get destroyed when program terminates. it has two different parts. HeaderLine(optional) & Body(Compulsory).

*Any value that comes to or goes from interanal table , that travels through headerline.\

*A related program is .

*declaration.

data: begin of inernaltable occurs 0,

x type c,

y type i,

end of itab.

*initializing headerline

internaltable-x = 'd'.

internaltable-y = 34.

*storing value into internal table

appene internaltable .

*reading internal table

loop at itab .

write: / internaltable-x, internaltable-y. "writes to output list

endloop.

Fields of Internal Tables

SY-TABIX

Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.

APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.

COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.

LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.

READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.

SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.

SY-TFILL

After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TFILL contains the number of lines in the relevant internal table.

SY-TLENG

After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the length of the lines in the relevant internal table.

SY-TOCCU

After the statements DESCRIBE TABLE, LOOP AT, and READ TABLE, SY-TLENG contains the initial amount of memory allocated to the relevant internal table.

Reward Points if it is usefull ...

u can use a system field sy-tabix

the value of which which will give u the no of lines in the internal table

Re: internal table

Former Member — Fri, 04 Jan 2008 10:27:00 GMT

U can use the describe statement as said above

or u can run the loop and after the execution of the loop

SY-DBCNT will give the no. of times theloop is executed or the No. of lines.

Reward points if found usefull.
