The Oracle Fusion BICC Extractor didn't previously extract columns marked in the metadata as "isPopulate": false
(non-populated columns). You can now choose to extract these as well by selecting the new extraction parameter Include Optional Columns during column configuration. When you do, we'll add the optional columns to the display and include them in the extraction by default. This can add a lot of extra columns, so we recommend you also select Customize Column Selection, then go through the updated list of columns and uncheck any that you don't want for your business case. For the extractor instructions, see Oracle Fusion Cloud BICC.
The BICC Extractor is in Limited Availability status. To get access as an early adopter, ask your Celonis point of contact.
