Can you share the calculated fields you are using? Or a sample solution in arena to understand the data granularity will also help.
In terms of execution, I can think of calculating the delta for each month and create another field to return the delta only for the last month. In that way we will not need to filter the data and the running sum stays unaffected.
Hi @Norbert,
Since we haven’t heard back, I’ll go ahead and close out this topic. However, if you have any additional questions, feel free to create a new post in the community and link this discussion for relevant information if needed.
