Greetings,
As per titled, here is the scenario (fictional)
1. Say 1st Oct we received an USA RIC code of XXX.A. On this same day, a client buys shares for this RIC code. The portfolio that we have right now in the system is based on XXX.A
2. Say 2 weeks later around 15th Oct we received an USA RIC code of YYY.A that is actually the same stock counter for XXX.A previously (RIC code changed for the same stock counter). Client now not able to view his/her shares portfolio due to different RIC code.
Is the scenario above possible? If so, we need to do data patching for the client's portfolio and we may need to know the indicator saying that there is a change for RIC code. For other info changes such as stock name, we able to map back using the RIC code but for RIC code changes itself, mapping for old RIC code maybe needed.
Ignore this question if this scenario is not possible. Thanks and have a pleasant day ahead.
