Help needed in coding

Hi Experts,

I have put a select statement in a function module which takes a lot of time to pick the data as it has got some complex selections in it.

Here is the code:

SELECT DOCNUM STATUS CREDAT CRETIM UPDDAT UPDTIM DIRECT IDOCTP MESTYP

FROM EDIDC

INTO CORRESPONDING FIELDS OF TABLE IT_EDIDC

FOR ALL ENTRIES IN IT_DOC

WHERE DOCNUM = IT_DOC-DOC_NUM AND STATUS = '03' OR STATUS = '16'

AND DIRECT = '1' AND IDOCTP = 'SHPMNT05' AND MESTYP = 'SHPADV' OR MESTYP = 'ZDESADV01'.

Can anyone help me how to simplify it and improve the performance there with?

Your help will be highly appreciated.

Thanking you in advance,

With Kind Regards,
