How to clear structure of TFDMemTable? Not only data like in EmptyDataset() method, but fields, indexes, filters, etc. too.

Is possible?

There are various ClearXxx methods for TFDMemTable, but it is not obvious which one(s) to call, or in which order, and if they actually reset the whole thing.
The above suggestions, on the other hand, are solid.

Hello Jaca! :)

There is no simple solution for that.

However, I would suggest basing your own solution on the CopyDataSet code.
Note that if you specify the coStructure parameter in the options of CopyDataSet method, you will get what you want.
Almost ;-)
