I have renamed an Item in Inventor. When I did this, the BOM structure disappeared from Vault. The only thing showing is the main item for the assembly, not any sub-items. Why is not the hole BOM list showing? Do I have to ad all the sub-items manually by adding new rows for every sub-item? Have anyone else had this problem? The assembly that was renamed had a very large file size. Could this have something to do with my problem?
