ECC6 - Line item display and Open item management Questions.

Question

Hi All,
For SAP ECC6, although I do not maintain line item display and open item management for Recon GL (for Debtor), I still can use FAGLB03 to view the GL balances and even Drill down to line item level by double click the value from FAGLB03 until line item level.
Questions:
Could anyone confirm whether my assumption below, true?
1) If Line item display (Tcode: FS00) is ON, then the data will be stored at table: BSIS
2) If NO open item management, then there should be no data to be stored at table BSAS for thaty particular GL account
3) BSAS will only have data, after clearing was carried out ... move from BSIS to BSAS.
In ECC 6
4) FAGLB03 can drill down to line item level, although the GL (Tcode: FS00) was NOT set open item management and line item display is because from FAGLB03 when drill down to line item level, it actually extract data from BSEG, right?
Additionally, we can use FBL3N to check the line item data for NON line item display GL as well.
In SAP R/3 4.7, if not mistaken, if the GL is NOT line item display and open item management, we cannot drill down the line item reading and CANNOT use FBL3N to check the line item data.
Kindly advise on these.
Thanks.

1) If Line item display (Tcode: FS00) is ON, then the data will be stored at table: BSIS
BSIS is an open items table. You can see all GL open items there. GL's which are not open item managed can't go here
2) If NO open item management, then there should be no data to be stored at table BSAS for thaty particular GL account
Yes. Your understanding is correct
3) BSAS will only have data, after clearing was carried out ... move from BSIS to BSAS.
Yes. In case of partial clearing data will be there in both the tables BSIS & BSAS
4) FAGLB03 can drill down to line item level, although the GL (Tcode: FS00) was NOT set open item management and line item display is because from FAGLB03 when drill down to line item level, it actually extract data from BSEG, right?
These are New GL reports and report is based on document split object. if your document split is active at segment level then you can see line item report at segment level using FAGLL03. These reports has no link to FS00 settings.
Hope this helps
