Problem with modifying Internal table using work area

[Former Member]

hi I am working on a BADI development

I have a trouble changing a particular parameter et_reqcap using work area

The parameter ET_REQCAP is of table type /SAPAPO/PPM_TTD_REQCAP...

and

ET_REQCAPX is of table type /SAPAPO/PPM_TTX_REQCAP

I dont have any syntax errors but when I am executing it the BADI triggers but I see the short dump.. You attempted to change, delete or create a line in the internal table "???", but no valid cursor exists for the table.

But will table type have a index ??

METHOD /sapapo/if_ex_ppm_calc~calc_bucket_cons.

  DATA: w_reqcap     TYPE /sapapo/reqcap,
        w_etreqcap_x TYPE /SAPAPO/PPM_TEX_REQCAP,
        w_etreqcap   TYPE /SAPAPO/PPM_TED_REQCAP. "/SAPAPO/PPM_TED_REQCAP

  LOOP AT it_reqcap INTO w_reqcap.
    IF w_reqcap-cap2 <> 1.

      w_etreqcap-cap2   = 1.
      w_etreqcap_x-cap2 = 'X'.

      MODIFY et_reqcap    from w_etreqcap   index 1 TRANSPORTING cap2.
      MODIFY et_reqcap_x  from w_etreqcap_x index 1 TRANSPORTING cap2.
    ENDIF.
  ENDLOOP.

  BREAK-POINT.

ENDMETHOD.

Hi!

Yes tables do have an index.

Within the LOOP, you can use the SY-TABIX variable, which points always to the last used record.

It is tricky, becaus if you give a READ TABLE statement within the LOOP, the SY-TABIX will point at the found record what READ TABLE provided.

I suggest you to put a break-point into the code and you will see, what is wrong.

I will check at runtime how many records IT_REQCAP possesses.. if it has only 1 during runtime all the time the I can directly read it and change the valyes of EQ_REQCAP..

this should simplify things.. anyways let me test it and then get back

this error happens beacuse your internal table et_reqcap_x is empty

so when using INDEX 1 for this table, a short dump happens

Does et_reqcap and et_reqcap_x contains data that needs to be modified? If that is, there should be no problem. An error will occur if it has no data and your pointing to index 1 which don't exist.

Or do you want to modify or save the data.

Use APPEND if you're inserting new data.
