Getting data from table BSEG taking too long ... any solutions.

Question

Hello people I am currently trying to get data from table BSEG for one particular G/L Account Number With restrictions using For All Entries.
The problem is that even with such tight restrictions its causing my report program to run way too slow. I put an option where you dont have to access table bseg. And it runs just fine. (all of this is done during PRD Server).
My question is
1.) How come BSEG seems to make the report slow, even though I put some tight restrictions. <b>Im using For All Entries where Zuonr eq i_tab-zuonr</b>it seems to work fine in DEV and <b>hkont EQ '0020103101'</b>(Customer Deposits).
2.) Is there a way for me to do the same thing as what I mentioned in #1 but only much faster.
Thanks guys and take care

Hi
It should be better you don't read BSEG table if you haven't the keys BUKRS and BELNR, because the reading could take many times if there are many hits.
If you want to find out the records of G/L Account it's better read the index table BSIS (for open items) and BSAS (for cleared items), here the field HKONT is a key (and ZUONR too). So you can improve the performance:
DATA: T_ITEMS LIKE STANDARD TABLE OF BSIS.
SELECT * FROM BSAS INTO TABLE T_ITEMS
  FOR ALL ENTRIES I_ITAB WHERE BUKRS = <BUKRS>
                           AND HKONT = '0020103101'
                           AND ZUONR = I_ITAB-ZUONR.
SELECT * FROM BSIS APPENDING TABLE T_ITEMS
  FOR ALL ENTRIES I_ITAB WHERE BUKRS = <BUKRS>
                           AND HKONT = '0020103101'
                           AND ZUONR = I_ITAB-ZUONR.
Remember every kind of item has an own index tables:
- BSIS/BSAS for G/L Account
- BSIK/BSAK for Vendor
- BSID/BSAD for Customer
These table have the same informations you can find out from BSEG and BKPF.
