The SWIFT IA services esmig.t2 and ebacl.e1s1 will introduce the "V-Shape" model with the HVPS migration to ISO20022 in Nov 2022, whereas the ESMIG and E1S1 Operators will always be the Requestor or Responder in the IA-header but not the "correspondent" bank intended in the message as the end counterpart in the transaction.
This correspondent institution is present in the BICFI tag of the BAH either as "From" or "To", but the MWH Message Warehouse doesn't keep so far an indexed column facilitating the db select search.
The request would be to add these indexed columns in MWH and include the logic in the product to fill in the MWH accordingly.
The delivery timeline is urgent, considering the User Testing phase in HVPS.
