Notes

The General page can vary according to the type of element you are adding an operation to; if defining operations for a data modeling table, see the Indexes, Triggers and Check Constraints topics
If you make changes and do not save them, the Cancel button prompts you to confirm or cancel the changes, whilst the Close button closes the dialog immediately and does not save the changes
If you are creating many operations, go to the Attribute/Operations page of the Options dialog (Tools | Options | Source Code Engineering | Attribute/Operations) and de-select the After save, re-select edited item checkbox; now, when you create an operation and click on the Save button, the dialog fields clear ready for you to enter the details of the next operation - this helps you when you want to create operations quickly and might not necessarily want to fully define each one as you create it
