How to get rows count of internal table in abap

Question

How do I get the row count of an internal table  I guess that I can loop on it  But there must be a saner way   I don t know if it makes a difference but the code should run on 4 6c version

if I understand your question correctly  you want to know the row number during a conditional loop over an internal table   You can use the system variable sy-tabix if you work with internal tables  Please refer to the ABAP documentation if you need more information  especially the chapter on internal table processing    Example   LOOP AT itab INTO workarea         WHERE tablefield   value        WRITE   This is row number    sy-tabix   ENDLOOP

You can use the following function    DESCRIBE TABLE  lt itab-Name gt  LINES  lt variable gt    After the call  variable contains the number of rows of the internal table

There is also a built-in function for this task   variable   lines  itab name      Just like the  pure  ABAP syntax described by IronGoofy  the function  lines     writes the number of lines of table itab name into the variable

data  vcnt 4    clear vcnt   LOOP at itab WHERE value    1     add 1 to vcnt  ENDLOOP    The answer will be 3   vcnt   3

I don t think there is a SAP parameter for that kind of result  Though the code below will deliver   LOOP AT intTab     AT END OF value       result   sy-tabix       write result       ENDAT   ENDLOOP

The functional module EM GET NUMBER OF ENTRIES will also provide the row count  It takes 1 parameter - the table name

Beside the recommended   DESCRIBE TABLE  lt itab-Name gt  LINES  lt variable gt    there is also the system variable SY-TFILL   From documentation      After the statements DESCRIBE TABLE  LOOP AT and READ TABLE  the number of rows of the accessed internal table    Example script   REPORT ytest   DATA pf exclude TYPE TABLE OF sy-ucomm WITH HEADER LINE   START-OF-SELECTION    APPEND  1  TO pf exclude    APPEND  2  TO pf exclude    APPEND  3  TO pf exclude    APPEND  4  TO pf exclude     WRITE     sy-tfill      sy-tfill     DESCRIBE TABLE pf exclude    WRITE     sy-tfill      sy-tfill   after describe table      sy-tfill   0   Reset   READ TABLE pf exclude INDEX 1 TRANSPORTING NO FIELDS    WRITE     sy-tfill      sy-tfill   after read table       sy-tfill   0   Reset   LOOP AT pf exclude      WRITE     sy-tfill      sy-tfill   in loop with   pf exclude      sy-tfill   0   Reset   ENDLOOP    The result   sy-tfill             0 sy-tfill             4  after describe tabl sy-tfill             4  after read table sy-tfill             4  in loop with 1 sy-tfill             0  in loop with 2 sy-tfill             0  in loop with 3 sy-tfill             0  in loop with 4   Please get attention of the value 0 for the 2nd entry  SY-TFILL is not updated with each step  only after the first loop   I recommend the usage SY-TFILL only  if you need it direct after the READ 1     If there are other commands between the READ and the usage of SY-TFILL  there is always the danger of a change of the system variable    1  or describe table

you can also use OPEN Sql to find the number of rows using the COUNT Grouping clause and also there is system field SY-LINCT to count the lines ROWS  of your table
