How to save an aggregate value in a table

[ServiceBreez]

Is there a solution to saving an aggregate value in a table?

Hello @ServiceBreez,

I had the same question but discovered that it is not possible to save aggregation values from the DataPage in the table.

As a workaround, it is possible to create an Application Task or Trigger that will calculate the SUM, for example, and insert/update it in the table.

it seems that this error occurs when you are trying to set one of your columns using the UPDATE statement with a value that uses an aggregate functions such as the SUM, MAX, or MIN. 

Therefore, it is not valid because in SQL it is impossible to use aggregate functions in update SET list. 

With this, you may try to do a use case is to add a so-called subquery (SELECT statement) and use this subquery in a JOIN. For more information,I have found a forunm post that is similar to your workflow. You may check this link as a reference:
