T-code
RSREQREDUCE (I wrote a blog post about it here)
that is present in classic BW systems (since version 74) was redesigned in case
of BW4 system. One of the main drivers for a change is that there are no cubes anymore
in BW4. The no of requests reduction incorporated into t-code RSA1 (even the
BW4’s RSA1 t-code is much more simplified then it use to be in classic BW) under
Housekeeping Tasks -> Request Housekeeping or it can be
called standalonly via t-code RSREQREDUCE.
In
contrary to classic BW the t-code does not display a list of critical data
targets right away once it was triggered. Instead, it shows a selection screen
which looks like following (screenshot based on BW4 2.0 SP06):
From
there it is possible to choose for which Object Type (aDSO, etc) operation of
reducing no of requests will be performed. It is possible to select also
InfoAreas as Object Type thus the operation can be one on several objects per
one shot.
Request
reduction operation can be done in simulation mode too (radio button Simulate
Housekeeping). That mode certainly helps to understand how many request can be
reduced. That is definitely helpful.
On
other hand, I liked that the t-code RSREQREDUCE displayed a list of critical
data targets right away once it was triggered in BW classic system. However, as
the functionality of t-code RSREQREDUCE was reworked the list of critical data
targets can be pulled up via ABAP program RSSTATMAN_REQ_REDUCE_DIALOG. Thus old
function is still there in BW4 system.
t-code
RSREQREDUCE coded in:
ABAP program ABAP FM/ABAP class
BW
classic RSSTATMAN_REQ_REDUCE_DIALOG RSSTATMAN_CRITICAL_TARGETS
BW4 RSPM_HOUSEKEEPING CL_RSPM_HOUSEKEEPING
Technically
the t-code is pointing ot ABAP program RSPM_HOUSEKEEPING and processing logic
is coded in ABAP class CL_RSPM_HOUSEKEEPING.
