Is there a way to see the "References" and "Referenced by" info when there are logics in DataManager blocks?
Like you can if you are in Field Manager in the actual report.
Would really like to clean up some massive report where the report writer queries a select * from many many tables. I can use the references/referenced by to see which field i need to keep.
If you are trying to reduce the number of fields used in your report and wish to preserve all the fields that are used in formulas in various DataManager blocks (reference in this sense) you could use the option from the DataManager interface: Tools>Other> Export formulas (all blocks)
The resulting .xml document will contain all the formulas, including the names of the referenced fields.
Hope this answers your question, otherwise please clarify what 'references' are.
In addition to the above, you can also change the view of the contents of the DataManager blocks using the Block Content option menu on the DataManager Toolbar. Changing from 'Configuration' to 'Field list' will allow you to see the fields passing through each block.
