Versions: FileMaker 16 and a number of earlier versions
This may be more a case of a statement lacking important details than an error.
I was reviewing the documentation in the on line help for GTRR and found this statement:
If you are filtering records in a portal, this script step exposes all the records, not just the filtered records.
This is not correct if GTRR is executed from the context of a portal row in the filtered portal. It is correct if the focus is not in the filtered portal's portal row, but this distinction is not made in this note entry and can thus lead the reader to incorrect conclusions about how this script step functions when employed from the filtered portal row context.
