When you run into the error message "No valid from or to certificate references", it means there’s a transaction that is missing the shareholding and certificate information. The error message provides the following information:

1. Affected Share Class

2. Transaction date

3. Transaction Type

We also provide a recommendation on the steps to fix. In this case it would be to delete the transaction.

Tip: The transaction is easily identifiable as you will notice both the acquired and disposed share amounts are 0, see screenshot below. To remove this transaction and clear the Data Integrity Issue simply click on the three dots on the far right of the transaction and hit Delete.
