Connecting your plant to SmartPlant introduces extra ramifications for projects in Drawing Manager. For instance, if you want to fetch a version of a drawing from your own project database (to roll back to an earlier version, for instance) the version creation timestamp must be later than the timestamp for the last publishing to SmartPlant.
When you are connected to SmartPlant and try to delete a fetched drawing that you have claimed items on, you must release all claims before you can do so. You must manually release these claims; Smart P&ID does not release your claims automatically. When you try to delete the fetched drawing, you see the message Release all claims prior to Delete. Likewise if a checked-out drawing has claimed items on it when you try to undo the checkout, the Remove from Project option on the Undo Checkout dialog box displays this message: Release all claims prior to Undo Checkout with this option.
You are always free to fetch a drawing in read-only or read/write mode, whether there are claimed items or not. However, SmartPlant does not allow a fetched drawing with read/write permissions to be overwritten when it is checked out or fetched again. In order not to replace an existing fetched drawing with read/write permissions in a project database when you check out a version of it, the Replace Existing P&ID option on the Check Out dialog box is never available. Likewise the OK button on the Fetch dialog box is not available if you select a drawing to fetch that you have already fetched with read/write permissions. Of course, if you really want to overwrite a drawing you already have fetched, you can delete the fetched version first.
