Hello Harish,
You need not equate import and export structures as you mentioned. Just mention like:AFRUD_EXP-fieldname = 'xyz'.. See this code below which I have tested for you, which is working fine.
IF SY-TCODE = 'IW41'.
AFRUD_EXP-ISDD = SY-DATUM - 3.
AFRUD_EXP-ISDZ = '060708'.
AFRUD_EXP-IEDD = SY-DATUM - 1.
AFRUD_EXP-IEDZ = '080910'.
AFRUD_EXP-BUDAT = SY-DATUM.
ENDIF.
and the result is
