Does anyone know what this error is and how to fix it:

=== Start Exception Extract

exception class : EFDException
exception message : [FireDAC][DatS]-2. Object [__MT__DEFAULT_] is not found.

thread $11498 (TInThreadWithTask):
00d19ed9 +0119 ODY.exe FireDAC.Stan.Error 189 +26 FDException

00d7e454 +0310 ODY.exe FireDAC.Comp.DataSet 2919 +57 TFDDataSet.OpenCursor
008a887d +0055 ODY.exe Data.DB 12663 +12 TDataSet.SetActive
00d7b4b3 +002b ODY.exe FireDAC.Comp.DataSet 1609 +7 TFDDataSet.SetActive
008a86b9 +0009 ODY.exe Data.DB 12619 +1 TDataSet.Open

=== End Exception Extract

The error occurs when I perform [TFDMemTable].Open at run-time.

At design-time [TFDMemTable].Open does not generate the error.

TIA

You should ask in the FireDAC group, where the author often answers questions.
FireDAC has nothing to do with FireMonkey.
