First of all:
Please stop using tables with header lines!

DATA:
  ls_te_po_header  TYPE bapi_te_mepoheader,
  ls_te_po_headerx TYPE bapi_te_mepoheaderx,
  lt_extensionin   TYPE bapiparex_tp.

ls_te_po_header-po_number  = '1234567890'.
ls_te_po_header-zztest     = 'Test'.
APPEND INITIAL LINE TO lt_extensionin ASSIGNING FIELD-SYMBOL(<fs_extensionin>).
<fs_extensionin>-structure   = 'BAPI_TE_MEPOHEADER'.
<fs_extensionin>-valuepart1  = ls_te_po_header.

* Fill X structure
ls_te_po_headerx-po_number = '1234567890'.
ls_te_po_headerx-zztest    = abap_true.
APPEND INITIAL LINE TO lt_extensionin ASSIGNING <fs_extensionin>.
<fs_extensionin>-structure   = 'BAPI_TE_MEPOHEADERX'.
<fs_extensionin>-valuepart1  = ls_te_po_headerx.
