Hi Sebastian,
I can imagine that a (very) simple key date valuation (no reset, no hedge mgmt) could be done in the BAdI TPM_TRL_MANIPULATE (method MANIPULATE_VALUATION_FLOWS + adaption of MANIPULATE_DERIVED_FLOWS to respect the former valuations).
But as said, so far, only the realizations (DBTs) are implemented as a sample BAdI code and no key date valuation, so this would be a customer own development.
Best regards,
Marie
