System Time during Full Installation

Question

Hi all,
During full installation (Device installation) in SAP ISU, system taking huge time, when I debugged it, I found that a select statement is taking most of the time.
T code : EG31
Main Program: SAPLIE01
INCLUDE LIE01U04. "EQUIPMENT_SUCCESSORS
Function Module: EQUIPMENT_SUCCESSORS
this is the code inside the function module.
standard SAP code----
selection of the newest time-segment of 'reading_date':
if 'reading_date' ::= ultimo
only one segment exists
else
the newest (last per day) is the one with 'datbi' > 'reading_date'
IF READING_DATE = MAX_DATE.
SELECT * FROM V_EQUI
INTO TABLE EQUI_TAB
WHERE HEQUI = EQUI_NO
AND DATBI = READING_DATE
ORDER BY EQUNR. "*<---
ELSE.
SELECT * FROM V_EQUI
INTO TABLE EQUI_TAB
WHERE HEQUI = EQUI_NO
AND DATAB <= READING_DATE
AND DATBI > READING_DATE
ORDER BY EQUNR. "*<---
ENDIF.
if somebody already faced this problems , please suggest me some solution to solve this issue.
thanks & regards,
Deepak.

Hi,
In this note the statement you mentioned
IF READING_DATE = MAX_DATE.
    SELECT * FROM V_EQUI
      INTO TABLE EQUI_TAB
      WHERE HEQUI = EQUI_NO
      AND   DATBI = READING_DATE
is replaced by
IF reading_date = max_date OR reading_date GE sy-datum.
    SELECT * FROM v_equi
      INTO TABLE equi_tab
      WHERE hequi = equi_no
      AND   datbi = max_date
