Some tokens in BOM editor are designed to work only insome specific BOM templates. This design is from the code and it can't beworkaround from the user.
In this case, the Detail title token works only inStructured list of drawings, a template which has behind the tokenconfiguration a specific code that allows it to make the structure grouping andalso allow this token to work. Therefore, in order to configure a BOM template inwhich this token evaluates, you need to start your new list from a copy of theStructured list of drawings, rather then Drawing index list.
The same logic is applied throughout BOM editor.For example you can't create a Structured list External list by copyingthe Beam list, because even if you configure the Beam list with the same tokensand groups, it will still not realize the grouping by assembly required by theStructured list.(Dimitru Berteanu)
