- [OpenAPI fragment](https://www.lusid.com/docs/api/lusid/endpoints/transaction-portfolios/UpsertVirtualTransactionOverride.json)
- [Rendered page](https://www.lusid.com/docs/api/lusid/endpoints/transaction-portfolios/UpsertVirtualTransactionOverride)

Creates or updates overrides and suppressions of virtual transactions generated by a single instrument
event. Overrides and suppressions are each keyed by the virtual transaction id they target. This is a
full replace of the previously stored overrides and suppressions for the targeted instrument event -
any previously stored entry not present in this request is removed.
Calling this endpoint again with the same virtual transaction id will replace the existing override or
suppression in place.
