error using data mode property: Optimize Query Execution

Summary:

Hello everyone, a few days ago I experienced a new situation.

I have a report that extracts a large amount of data (over 100,000). I tried to optimize the execution time using a property of the data model. The execution time is faster, the number of records is the same, but for some reason the information varies in some cases. That is, if I compare the normal execution with the execution using that property, the data information varies in some records, but the amount is the same.
Do you know why this behavior occurs?

In my case, using that property does optimize the execution time; the number of records is the same, but the information varies.
