ORDCHG Extension Idoc problem

Hi SAP GURU'S

I did below steps for extension of ORDCHG Message type 

1. WE31 - Created A segment(YTEST) with additional fields.

2. WE20 - Created the Extension(ZORDERS05) for the given Basic type ORDERS05.

        2.1    added the custom segment(YTEST) as the child segment to the segment ( E1EDP01)

3. Released the custom segment (YTEST) and the Extension (ZORDERS05).

4. WE82 - Assigned Basic type to extension / messages( For Both messages ORDCHG&ORDERS)

5. WE30 - Checked and Transported IDoc extension

                 5.1  Given the Extension Name(ZORDERS05)

                 5.2 In the menu Path :  Development Object -- >Check (Ensure that there are no errors or warnings)

6. WE20 - Now in the Partner Profile  added the Extension(ZORDERS05) in the Message control data and Saved it(For Both messages ORDCHG&ORDERS).

I added code In BADI (IDOC_DATA_INSERT)  for YTEST Segment .

case control-direct.
     when '1'.                         " Outbound
       case control-rcvprn .
         when 'XXXXX'.             " Partenr
           case control-mestyp.
                 when 'ORDERS' or 'ORDCHG'.           " Message type

If Control-cimtyp = 'ZORDERS05.

loop at data into ls_data where segnam = 'E1EDP01'.
                     ls_seg_num-segnum = ls_data-segnum.
                     append ls_seg_num to lt_seg_num .
                   endloop .

                   lv_count = 1.
                   loop at lt_ekpo into ls_ekpo.
                     read table lt_seg_num into ls_seg_num index lv_count.
* filling Maximo PR field name and value
                     ls_y1mm_maximo_pr-item = ls_ekpo-bnfpo.
                     ls_y1mm_maximo_pr-bednr = ls_ekpo-bednr.
                     ls_y1mm_maximo_pr-banfn = ls_ekpo-banfn.

                     clear ls_new_segment1.
* Data inserting into zsegments
                     ls_new_segment1-segnam = lco_zsegment1.
                     ls_new_segment1-counter = '000' .
                     ls_new_segment1-sdata = ls_y1mm_maximo_pr.
                     ls_new_segment1-segnum = ls_seg_num-segnum.

                     if ls_new_segment1  is not initial.
                       have_to_change = 'X'.
                       append ls_new_segment1 to new_entries.
                     endif.
                     clear : ls_y1mm_maximo_pr.
                     lv_count = lv_count + 1.
                   endloop.

     Endif.
Endcase.

Note : This is working for PO Creation( ORDERS Msg) , I can See the "Control-cimtyp = 'ZORDERS05'"  , But it is n

ot working for ORDCHG Msg type , I did the above config for  both message types .

When ever PO change I could nt see the extension Idoc( ZORDERS05) , Even in WE05 Tcode , But Idoc is tiggering with out adding adding additional segment(YTEST) .

Please kindly help me out .,

Thanks in advance,

Krishna Kothaluru.
