The Intergraph Smart® P&ID Duplicate Item Tag Report Utility generates a report in the form of a Microsoft® Excel workbook that lists instruments, piping components and equipment in your active plant that have the same item tag. Since it is possible to archive a drawing and then delete an item from that drawing, it is possible for the item tag for that item to be assigned to another item that is placed subsequent to the first. However, if you retrieve the drawing from the archive, there are two items with the same item tag. This report lists those instruments and piping components, and you can edit the item properties so that your data remains coherent.
The report is stored in your temporary directory: temp\<YourPlant>-DuplicateTags.xls. Instruments are on the first worksheet, piping components are on the second worksheet, and equipment is on the third worksheet. You can use this report to ascertain exactly which items have duplicate item tags so that you can find these items in Smart P&ID and return the tags to a unique state.
