When you Assign Items in Vault Professional 2012, using the Auto-select first duplicates option you will see the following result.
Notice that the last Item Number for the 444.ipt file, will be replaced by another Item Number (100001). But 100001 will be replaced with Item Number 123456, causing a cyclic relationship. Indeed, if you click Finish at this point you will get this message.
The reason for this is that the Item Assign wizard will query the Database for any existing Item Numbers that have been already committed. Because the Item Number 123456 has not been committed to the Database it will not be returned by the query, causing the behaviour.
Autodesk is considering improving this behaviour in a future release.
Two possible workflows to overcome this problem are:
- Before assigning an Item to the assembly, Assign Item to one of the children first
- Right click the Replace With cell, click Select Replacement Item, then untick the Item Number 10001, or whatever it is in your system. This excludes it from being included by the Auto-select first duplicates subroutine.
