expandAllData API method doesn’t work correctly in compact form layout for reports with high number of rows.
In our case we build a report with ~600k rows(6 dimensions fields and 8 value fields) and on expandAllData method call it expand report nodes only partly, most of data remain collapsed. Also you unable to expand collapsed nodes manually(on node click). In classic form layout for same report expandAllData API method work correctly and expand all nodes.
Other one problem is that expandAllData API method is slow(it takes 2-3 min to expand all rows) and page stops responding every time you call it.
Thank you for writing to us.
We would like to point out that
expandAllData is a heavy operation and the more dimensions are selected, the heavier it is.
For a big amount of data, we suggest avoiding this operation.
However, the issue with manual expanding of nodes is not the expected behavior.
Could you please let us know if this problem occurs even when
expandAllData is not called?
We are looking forward to hearing from you.
