If you have an action button in your TM1 Prespectives report that runs some TI and that TI uses the entered values in the given Perspectives report, the sheet needs to be recalculated in order those values to be available in the TI process. Simply go to action button properties, open Calculate tab and select “Automatically Recalculate Sheet”.
It will recalculate the report before running a TI process and solve the issue.
