Hello Gents, Just wanted to share my latest experience with by now the (in)famous SP2 for 2004. After upgrade, creating a BOM (sw style) in any assy. drawing did NOT work. All attempts to insert a SW BOM resulted in an empty table. Empty and un-editable, that is...:). Any attempts to edit an existing BOM did screw up the older BOM too. The only functioning thing was the Excel style BOM (old) with all its well known peculiarities. I had to un-install 2004 and re-install it with sp1 only. Back in business. Any ideas on the subject (or similar experiences) ? Thanks !
