Hello Hari, hello Grigoriy,
the VTBFHAPO* tables will NOT have the interest flows for securities - they are not based on a single deal, but on the whole position cash flow.
You will find them in tpm40: TRS* tables (e.g. TRST_CLASFLO or view TRSV_POSFLOW) and also in tpm13 (TRL* tables, e.g. TRLV_TRANS_POS) .
The LDBs from the transaction manager provide a view on these tables, please see
Information System - SAP Library .
Best regards,
Marie
