Need to alter the tdline for E1EDKT2

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.
