Hi giriraj.gupta1,
ODF_OBJECT_INSTANCE_MAPPING table is used for the link between INV_INVESTMENTS table and FIN_FINANCIALS table.
The following query links both tables and I hope that the information helps you.
select I.Id, I.CODE, I.NAME
from INV_INVESTMENTS I, ODF_OBJECT_INSTANCE_MAPPING M, fIN_FINANCIALS F
where M.SECONDARY_OBJECT_INSTANCE_CODE = 'financials'
AND M.PRIMARY_OBJECT_INSTANCE_CODE = I.ODF_OBJECT_CODE
AND M.PRIMARY_OBJECT_INSTANCE_ID = I.ID
AND M.SECONDARY_OBJECT_INSTANCE_ID = F.ID
Regards,
