you are able to define unique and non-unique indices but there is no selection for bitmap indices in ODI 11g 126.96.36.199.
In Topology manager, I find a node "Index Type" under the Oracle technology which offers "Bitmap" as a choice. But I have no idea how to use it.
Any idea is appreciated, my customer expects it to be defined in ODI.
Check your knowledge modules - you might need to modify / add a create index step , I usually pin it to one of the UDx flags in the interface and use that to control what columns are included in the index.
