table invalid index

[Former Member]

Hello everyone.

I have a webdynpro program which call a pdf form.

sometimes,some of our users are getting a dump "TABLE_INVALID_INDEX".

The error is on row which try to delete itab on specific index . (delete itab index lv_idx).

When the same pdf is being called from a regular sap program (not webdynpro), it runs OK.

Any ideas what can be the problem?

thanks

Hi ami,

The lv_indx value 0 is the reason for dump.

you put condition before delete statement like below.

if lv_index is not initial.

delete itab index lv_index.

endif.

Hi Ami,

Either lv_idx has value 0 or the value which is more than the no. of lines in table.

You need to find out how the value lv_idx is getting passed/filled.

Try to check condition before deleting as below

describe itab.

if lv_idx > 0 and lv_idx <= sy-tfill.

delete itab index lv_idx

endif.

Hi,

I think there is no conditional check before deleting records from internal table.If Delete statement is written with index as below,

For eg: DELETE itab INDEX lv_index.

In above example, if the index value SY-TABIX = 0, then the error may occur.So that you may be able to analyze why the index value is Zero.

Hi ami,

Could you tell me what value you are getting in lv_idx?

What is data type of lv_idx?

iv_idx is from type i.

I think the value i'm getting is 0 but i'm not sure because i can not put debug on that code

because it does not happen consistently and not for all users.

Hi,

Try this  and check.

DATA LV_INDEX TYPE SY-TABIX.
