I have two bookmarks in a DXP file -- CurveDraw1 and CurveDraw2. I recently noticed this error message when engaging each of these bookmarks my DxP file.
Seeing the error message was strange because the bookmark worked as intended. However, with bookmarks, you must remember that they are capturing all filter settings for all tables. In this case, I am getting the bookmark warning/error because I used to have a table called RAVEN_BAKKEN UL TYPE_CRUVE in the DXP file that doesn't exist anymore. When I saved the bookmark, Spotfire recorded filter settings for this table (of which there are none). I later deleted the table, which doesn't technically impact the bookmark, but Spotfire thinks something is missing.
The fix for this is to engage and then update the bookmark.
