Hi,
the transaction S_ALR_87008537 could be used to define reference interest rates.
now, there are different options available how to update these reference interest rates into transaction - this is under IMG -> ... -> TRM -> Transaction Manager -> General settings -> Organization -> Define Company Code Additional Data -> see a field 'Planned record update' in the area 'Settings for variable interest rates' (see a screenshot below).
despite the fact, that reference rates in a transaction could be updated automatically as in your setup, you still need to fix these via TI10 (by manual entry) or
(update from the reference interest rate table) in order to able to post respective interest flows.
Kind regards,
Renatas
