Here is sample code.
tables:edid4,edidc,likp.
types:begin of ty_likp,
      vbeln type vbeln_vl, "delivery no
end of ty_likp.
data:it_likp type table of ty_likp,
     wa_likp type ty_likp.
types:begin of ty_edidc,
      DOCNUM type EDI_DOCNUM,
      MESTYP type EDI_MESTYP,
      IDOCTP type EDI_IDOCTP,
end of ty_edidc.
data:it_edidc type table of ty_edidc,
     wa_edidc type ty_edidc.
types:begin of ty_edid4,
      DOCNUM type EDI_DOCNUM,
      sdata type EDI_SDATA,
      segnam type edi_segnam,
end of ty_edid4.
data:it_edid4 type table of ty_edid4,
     wa_edid4 type ty_edid4.
select DOCNUM
        mestyp
        idoctp
        from
        edidc into table it_edidc
        where mestyp = 'DESADV'
        AND IDOCTP = 'DELVRY03'.

Hi,
after this...try like this
if not it_edidc[] is initial.
select segnam sdata from edid4 into table it_edid4
for all entries in it_edidc
where docnum = it_edidc-docnum.
endif.
now u need to loop ur delivery numbers table and also the internal table it_edid4 and check the segment where ur getting the delivery number.
Loop at it_delivery
Loop at it_edid4.
if it_edid4-segnam = <give the segment name where delivery number exists>.
move : it_edid4-sdata to wa_edid4-sdata.
now check the delivery number with it_delivery-deliveryno.
endf.
endloop.
endloop.
