Ways of calculating Running Count to import data into Multi-Line models

I’ve nicked the term “Multi-Line” model out from some cognos best practices presentations. Never known it was called that way ) Multi-Line is only way to go when you have a potentially huge dimension only a tiny bit of which should be available to end-user at a time. Like employee planning, whole dimension of 10k [...]

Open Source BPMS

Intalio makes Open Source Business Process Management (BPM is Business Performance Management, adding an S you get a completely different product). It seems that OS community lacks only some OLAP-server with breakback(write-back, back-solve, call whether you like) to get the planning\budgeting system. Mondrian cannot do that, as far as I know.

Stable as hell (stopping only for updates), working on slow PCs (a usual desktop). We’re using Jira for about 3 years now, and it’s just the way it should be. Recently discovered Jelly, so [...]

Back from vacations. Digging piled mail and feeds. Adaptive Planning – first open-source planning application? (just a less-featured version, but that’s a start). Compiere + some OS BI (including planning) can be a solution in future.
