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.

Answer 1

You can use the following function:

 DESCRIBE TABLE <itab-Name> LINES <variable>

After the call, variable contains the number of rows of the internal table .

Answer 2

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.

Answer 3

HOW TO GET THE NUMBER OF ROW OF ITAB AT SOME WHERE CONDITION.

Answer 4

Hello OMER,

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.

Answer 5

Hi,

I think that OMMER needs to know how to get the total number of rows of itab when a condition is evaluated:

LOOP at itab WHERE value = '1'. ... ENDLOOP.

... if itab has this values:

---

value | field1 | field2 | field3 |

1 | XX | yy | zz |

1 | AA | BB | CC |

1 | FF | EE | DD |

2 | XX | bb | zz |

... then the result, would be 3....

Is there in SAP a parameter that return this result???

Thanks....
