Hi Suman,
Thanks for the reply and time.
I also preferred First approach only. But it is not just matter of adding one more look up from DSO2 to create new record. We need to check Valid From &To dates for both TDA1 and TDA2 and if they are different then only need to add extra record or else need to modify existing record. In this scenario there might be unknown/unexpected consequences due to derivation of Valid From & To dates from different sources and with that extra record if getting added.
Appreciate if you could provide comments on -ve consequences if any with this extra record.
Thanks in advance for your understanding.
Regards,
