I was following the getting started section and created a design-time login for my Data Abstract table, and I entered the wrong schema by accident. Or rather i forgot that mine was named differently than in the table. Now when I want to edit the design time connection it gives me a nice little “Cannot find the schema Tasks” exception and prevents me from editing the incorrect schema.
Does anyone know of a way to reset this data on Delphi 10 Data Abstract?
If I understand you problem correctly, right mouse click on the TDAMemDataTable and select “Retrieve DataTable Schema”

Thanks a lot! 
You can also accomplish this at run time with the Method : “LoadSchema”
Retreive datatable schema has started to give me the same error

Edit: I’m not seeing any method of clearing it or directly deleting it so I’m resetting my essentially corrupted project 
Edit2: I miss clicked on Retrieve DataTable Schema on project v2 and now design time has been nuked on try 2 as well -.-
I probably missed something, but why you can’t just change table.LogicalName to valid name and then press Retrieve DataTable Schema for retrieving fields?
