Modify internal table embedded in internal table as field

Question

Hi Experts,
I am using function module CRM_DNO_READ_ORDER_TEXT.
One of the output table of this fm is  ET_ALLTEXTS whixh is of structure COMT_TEXT_TEXTDATA_T.
This structure has two fields one is GUI and other is LINES which itself contains the table in it.
I want to delete one row from the data of this LINES table in main table ET_ALLTEXTS .
Actually, this LINES table contains the texts entered by user from some application. So i want to edit the text.
Pls help me..this is very complicated.
thnx
DIvya

I guess Nilesh is right, there is something wrong with your declaration. Me for one, I've tried to reproduce your problem and I don't see any problem here. How did you declare your internal table for example?
When you want to delete a line from table LINES you can't just say:
delete et_alltexts-lines index 1.
Because this will give you the error message with 'table without header line....". Instead you first have to loop at this ET_ALLTEXTS internal table and only then you have access to the individual lines, which is an internal table as well. The following is only an example, but it should be helpful:
DATA: gv_header_guid TYPE crmt_object_guid.
DATA: gt_textdata    TYPE comt_text_textdata_t ,
      gt_alltexts    TYPE comt_text_textdata_t.
FIELD-SYMBOLS: <alltext>     LIKE LINE OF gt_alltexts.
CALL FUNCTION 'CRM_DNO_READ_ORDER_TEXT'
  EXPORTING
    iv_header_guid = gv_header_guid
  IMPORTING
    et_textdata    = gt_textdata
    et_alltexts    = gt_alltexts.
LOOP AT gt_alltexts ASSIGNING <alltext>.
  DELETE <alltext>-lines INDEX 1.
ENDLOOP.
