Hi Hrishikesh,
Could you post the bursting rules you are using? That would help giving you specific tips and guidance.
In general you should use the dmslocation section in the burst rules. In general that would be something like this:
<dmslocation>
<locnrule elementname="bookmap" location="bookmaps" />
<locnrule elementname="topic" location="topics" />
<locnrule location="Graphics" sourcetype="graphic" />
</dmslocation>
The folders given in the dmslocation rule are independent of the container in Windchill where the objects would be stored - so depending on your current connection / workspace Editor would use that container (Library, Product) and look for the folders defined in the dmslocation rules.
You might need 2 different bursting rule files - one for the ditabase doctype which covers all topic types (including subtypes) and one for the "bookmap" doctype, if you are using this DITA specialization.
Hope this helps. As mentioned - for more specific guidance it would help if you could post your existing bursting rules.
Kind regards
Sirko
