In some Manufacturing or Customer Service BOM use cases, need to create some recursive BOMs.
For example, retrofit of an existing Part
This Part can then be added under herself or under one of her sublevels.
Today Windchill (PSB or MPMLink ) controls that a recursive link is not created in the BOM. But this control can be easily workaround. In fact only loop link on himself is forbiden (since 9.1)
enhancement request: Create an Org preference, to be able to disable this control. or at least to change this popup window as a Warning instead of a veto.
Recursive BOMs should be controled in downstream chain:
-the PSB or where used table already stop the BOM explosion
-Cognos BOM reports
- what about other uses cases ? ESI , effectivities propagation , etc ...
example in PSB 10.2
SAP ERP allow that. specifed by a checkbox "allow recursive" on the BOM usage link
