Bypassing BSEG!

Question

HI !
is there any method to by pass FI TABLE BSEG as , pcl1,pcl2,pcl3 of HR are used to be accessed by RPCS using macros , is there any functinality for FI table BSEG , (e.g bseg cluster table can be directly accessed or by passed from database directly insted of moving it to memeory and again accessing ) as done by above RPCS using macros for pal1,pcl2,pcl3 etc ! means we can access any componenet from BSEG cluster table directly by efficent manner instead of moving whole data to memeory and then filtering it ! i am attachin some data for pcl1,pcl2 ,pcl3 it used to be accesed
}example starts here.
pCL1 is the database for HR application areas.It contains information
regarding the time recording.
PCL2 contains information regarding payroll accounting.
PCL3 contains applicant data.
PCL4 contains change documents for HR master data.
Cluster rx contains the payroll results for country x according to table
T500l.
The clusters can be called from macros.
RP-IMP-Cn-xx ( n = 1,2,3,4 and xx is cluster)
When macro is used to import data,it is not directly get from database table PCL,
instead it checks for the buffer directory whether it contains it in main memory.
if it is there it takes it from main memory..otherwise it reads from PCL to main
memory and from there to the report.
Standard import programs follow the naming convention RPCLSTxx..xx is cluster.
RP-EXP-Cn-xx ( n = 1,2,3,4 and xx is cluster)

Hi Prashanth,
    While writing a select statement, to access the record quickly its better to mention all the fields of a primary key.If not possible, atleast the fields mentioned in the where statement should be in order.
See in you select statement ebeln,ebelp are compared first and belnr is compared last.Compare them in the order in which they are in the table.
Even while selecting the data, gjahr matnr wrbtr is not matching with the table order.
Please change the order of the fields and check the performance.Surely it will not take time as much as before.
select belnr gjahr wrbtr sgtxt matnr ebeln ebelp prctr
from bseg into corresponding fields of table ist_bseg
for all entries in ist_mseg
where
belnr between '0002800000' and '0002899999'
and  matnr = ist_mseg-matnr
and  ebeln = ist_mseg-ebeln
and  ebelp = ist_mseg-ebelp.
Hope this is helpful.
Please let me know if any issues....
