Hi Community,
I have this little visual that uses the periodOverPeriodLastValue function. When I add the field with the truncDate the calculated field with the periodOverPeriodLastValue shows nothing. But it has nothing to do with the calculation.
But when I try to use the period-function in combination with the truncDate function the following happens:
Is this a bug or can someone explain this behaviour?
Best regards,
Nico
Hello @Nico, this is really interesting. There are a few things I want to mention. As for the truncDate function within your periodOverPeriod calculation, I have seen similar issues before. Whenever I am using a LAC-W aggregation, and I need to partition by something like a Date Month, I will create a separate calculated field, Date Month = truncDate('MM', {Date}) , that I can then reference in my sumOver function, sumOver({Sales}, [{Date Month}], PRE_AGG).
Utilizing the calculations like that avoids running into any errors. I noticed in my own testing that periodOverPeriod functions tend to have the same issue. I tried using a truncDate calc in the function and replaced it with a calculated field and it worked without an issue:
truncDate in periodOverPeriod:
Splitting the calculations:
I also think the first error is just an issue with the table visual. It seems to be confused on how to group the 2 different date values with the periodOverPeriod aggregation. If you really want to show that 2nd date, you may be able to convert the value to a string to bypass the issue.
I also created an analysis in Arena to test out some of these calculations. If you have any further questions, we can work from here to test out possible solutions.

Thank you!
Hello @Nico, I wanted to follow-up since we have not heard back from you. Did my last response help resolve the issue you are facing? If so, please mark my reply as the solution. Otherwise, please provide some more information about the problem you are facing and I can help guide you further.

Hi @DylanM
Thank you for your answer. I think your answer is helpfull. I just saw this behaivour and do not have to solve it in a dashboard right now.
Do you think it is a bug that the development team should know?
Best regards,
Nico
Hello @Nico, I definitely think this is something worth sending to our support team! I have also experienced this issue in my development so it would be nice if we could utilize the truncDate function directly in the periodOverPeriod or LAC-W aggregations rather than creating 2 separate fields.
I appreciate your feedback. I will tag this topic as a feature request. Let me know if you have any remaining questions, otherwise I will archive this topic for our support team.
Thank you!
