Hi @Zolotoy ,
Unfortunately, one data area in SSRS will point to only one Dataset. If you want to get data from two Datasets, you need to create another Dataset that will merge queries from the other two Datasets and aggregate the data into one Dataset.
In addition, in some cases, you could also choose to use expressions to get some data in the second Dataset, such as Lookup FunctionćLookupSet FunctionćMultilookup Function.
Best Regards,
Joy
