Hi Vadim,
I also tried to manually create the local member then typed in the EPM formula in the "Edit" dialog box but the result is same - the figure is incorrect after report collapse because the excel cell reference moves after collapse. I'm attaching a few screenshots.
After Expand
After Collapse
EPM Local Member Setting
Account Member Settings
Another thing I noticed that node TOTAL REVENUE is collapsed by default but other parent nodes are expanded by default i.e. when I launch the report.
Regards
Sougata.
