Need to alter the tdline for E1EDKT2

Question

Hello Team,
I have a requirement such as this.
I need to loop the internal table idoc_data , search for segment E1EDKT2, and alter the tdline for the segment, is there an efficient way of doing this?
LOOP at IDOC_DATA
assigning <FS_IDOC_DATA> where  SEGNAM = ‘E1EDKT2’
  if sy-tabix = 1,
concatenate ‘XXXXXX:’ E1EDKT2-TDLINE into E1EDKT2-TDLINE.
endif.
endloop.
Is there an efficient way that i can access the segment of the row in idoc_data and alter the tdline?
would greatly appreciate any help on this.

Hello Ramiwal,
You can try with the statement MODIFY itab with itab_lines.
Refer to the SAP help for the statement as below.
MODIFY itab - itab_lines
Syntax
... itab FROM wa TRANSPORTING comp1 comp2 ... WHERE log_exp.
Effect
With these additions the MODIFY statement assigns the content of the comp1 comp2 ... components of the wa work area specified after TRANSPORTING to all lines in the itab table that meet the logical condition log_exp. The wa workarea must be compatib
The TRANSPORTING addition has the same effect as changing individual lines. The WHERE addition can only be specified together with the TRANSPORTING addition. After WHERE, any logical expression can be specified in which the first operand of each individual comparison
Example
Change the contents of the planetype component for all lines in the sflight_tab internal table in which this component contains the value p_plane1 to the value p_plane2.
PARAMETERS: p_carrid TYPE sflight-carrid,
            p_connid TYPE sflight-connid,
            p_plane1 TYPE sflight-planetype,
            p_plane2 TYPE sflight-planetype.
DATA sflight_tab TYPE SORTED TABLE OF sflight
                 WITH UNIQUE KEY carrid connid fldate.
DATA sflight_wa TYPE sflight.
SELECT *
       FROM sflight
       INTO TABLE sflight_tab
       WHERE carrid = p_carrid AND
             connid = p_connid.
sflight_wa-planetype = p_plane2.
MODIFY sflight_tab FROM sflight_wa
       TRANSPORTING planetype WHERE planetype = p_plane1.
wa = <--- required changes.
MODIFY idoc_data FROM wa TRANSPORTING tdline WHERE segnam = 'E1EDKT2'.
