Summary
Details of HDL messages that are being changedContent
In 20C the following messages are being replaced:
A logical start date is required
You have provided a date-effective row that starts on {FIRST_ROW_START_DATE}, for an existing record that doesn't start until {DB_LOGICAL_START_DATE}.
Another record with the same identifier exists, starting on {DB_LOGICAL_START_DATE}. If you're attempting to create a new record, provide a unique reference using the source key or user key attributes. To change the existing record to have an earlier start date, supply the ReplaceFirstEffectiveStartDate attribute with a value of Y. Use the View Business Objects task to confirm that this object supports a change to the earliest start date.
