This hard warning message reads:
For transactions data accuracy, imported merger transactions should be deleted and re-generated using the Morningstar Office Merger/Exchange Wizard. Please refer to the Corporate Action Warehouse for more information and resources.
This indicates that this transaction is the result of a corporate action, and recognized as such by Morningstar. In order to have the most accurate information, you must detail the transaction(s) using the Corporate Actions Wizard. See the Merger/Exchange Wizard help for more information.
The Merger/Exchange Wizard is recommended for these reasons:
The merger transactions sent from the custodian will lack original cost basis and original date information.
The merger transactioins from your custodian will not balance each other and can cause non-consistent data warnings on performance reports.
With the wizard, the Cash-in-Lieu transaction will be treated as a sell of fractional shares (realized gain) rather than a distribution or out-of-pocket deposit.
