When using the Report Wizard from, Model | Report | .... | Generate ER Diagram, there is no display of ER Diagram in report: "not enough resources to complete command"
The Toad Data Modeler cannot manage to generate an image of the ER Diagram when the file is too big.
WORKAROUND:
Open the Report Wizard and clear the option "Generate ER Diagram",
the HTML report will be generated,without a screenshot of the ER Diagram.
STATUS:
Waiting for a fix to be released in a future version of the Toad Data Modeler.
