For more information see [IMS Main Screen - Toolbar](/v414/docs/basic-navigation-other-main-menu-options#6-toolbar). Take note: - Normally a LOPA is active after the first Final Approval. - To delete a LOPA it must  be in Draft (and Inactive). Thus, Final Approved LOPAs cannot be deleted. - You can use the calculate button![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/lopa-menu-toolbar-image-ylnzudpj.png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A45%3A30Z&se=2026-10-28T17%3A45%3A30Z&sr=c&sp=r&sig=ItpGm8WPdCrozOoYkwwQdJHtFCJ0CBB5Km%2BSx1aSOHQ%3D) to Calculate the SIL gap for selected LOPAs. - To learn more about deleting and retiring LOPAs see [Deletion & Retirement (SIS Object Lifecycle Management)](/v414/docs/deletion-retirement-sis-object-lifecycle-management). ### Copying and Pasting LOPAs LOPAs can be copied and pasted via the LOPA Main Screen toolbar's *Copy* and *Paste* buttons. The data will be handled as follows: - If the copied LOPA has a link to a HAZOP, the link will be severed, and any linked information will be removed from the common details of the new LOPA. - If the copied LOPA includes a SIF, a duplicate of the SIF will be created as a standard barrier in the new LOPA. Additionally, the PFD values (L and H) will be reset to 1.00E+00, and the calculate button will turn red, indicating a recalculation is necessary. - Initiating Events, Barriers, and Condition Modifiers in the copied LOPA will retain the same text, validity, frequencies, and PFDs as in the original LOPA. - All notes, attachments, revisions, recommendations, SCEs, and actions will be removed. ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic%201.emf(2).png?sv=2026-02-06&spr=https&st=2026-10-28T16%3A45%3A30Z&se=2026-10-28T17%3A45%3A30Z&sr=c&sp=r&sig=ItpGm8WPdCrozOoYkwwQdJHtFCJ0CBB5Km%2BSx1aSOHQ%3D)The Copy and Paste functions in the LOPA Main Screen toolbar.  ## Filtering LOPAs From the LOPA overview page, several filters can be used to drill down the search results for the shown list of LOPAs. Filters include items such as: - Date Range, - Active, - Approved Status, - Has “Not Valid” Barriers, - LOPA with SIF, - Etc.
