TSCOR0123 The file descriptor with the ID {0} could not be found among previous output parameters.

A file input parameter was modeled with the attribute "Parameter_From" set to "Previous_Tool" but the file descriptor was never returned as an output parameter by a previous executed tool in this action.

Model Administrator Response:

Either set the "Parameter_From" value of the file input parameter to "Context" or make sure that the file descriptor is returned as an output parameter by a previous tool in the action sequence. Setting the "Parameter_From" attribute to "Context" requires the file descriptor to have a valid "Name_Physical" attribute value.
