From 184.108.40.206 the way help is delivered has changed and to be honest I know it is all over the documentation but I think through my own ignorance I pretty much ignored the following statement.
The issue relates to starting the Essbase OPMN service but I believe it is valid for any of the 11.1.2.x EPM OPMN services.
After the initial configuration of Essbase an OPMN windows service will be created and set to be controlled by the Local System account.
The loading of meta/data can now be achieved from a relational source but unfortunately the new functionality of extracting data can only be to a target flat file, I am sure in future releases a relational target option will be added.
The issue definitely exists on 220.127.116.11 and I believe it exists in unpatched 18.104.22.168 and 10g.
Say you want to extract the hierarchy from an attribute dimension from an essbase outline it certainly should be possible using the “LKM Hyperion Essbase METADATA to SQL”
I am not going to cover any of the properties again so if you have not done so it is probably worth having a read of the last blog.
