Hi,

You can DESCRIBE the internal table and find out the number of records in the internal table.

The you can use that number as your index in the do while statement.

DO... WHILE SY-TABIX <= TableIndex.

Hi C,

Since the internal table size may vary, you can use the

DESCRIBE

statement....This will give the current size of the internal table.

Once you capture the size, then you can use the below given code..

DO...While sy-tabix <= v_index

Here v_index will hold the maximum lines in the internal table....so this loop will be executed until the end of the internal table.

Best Regards,

Ram.

Hi,

First count the number of lines in internal tables using

describe table it_table lines lv_value.

now the variable lv_value will holds the number of lines in internal table ..

Then do the required do and while conditions based in this count.

Thanks,

Describe table tablename lines v_line.

Data count type i value 0.

while count < v_line.

endwhile.

Form code_to_write.

count = count + 1.

endform.

This work exactly as u want.

That is the reason i recommended you to use the describe statement so that you get the number of lines in the internal table at runtime in a variable.

Anyways, I don't know why you want to do this. As Matt explained LOOP AT ... ENDLOOP should also be sufficient.

Exactly, from what I can judge from reading the first post. I do not understand why anyone would want to make work for themselves by avoiding the simple solution and making things more complicated.
