Base Transaction in Data Providers

Since GeneXus X Evolution 3 you can define into the Data Provider Group statement the Transaction name or Transaction.Level name that you want to use as the Base Table to be navigated.

This concept is called Base Transaction and in the Data Provider Group statement it must be preceded by the From clause.

Example

Invoices
{
   InvoiceItem From Invoice
   {
      CustomerName
      InvoiceDate
   }
}

This example will return a collection of invoices.
