Starting in BI 4.1 SP03, Developers have introduced a Formula Rewrite Tool to automatically correct formulas in Web Intelligence documents that are affected by known calcluation engine changes.
There are 3 formulas the rewrite tool can auto correct when enabled:
- Running Calculations
- Where operator on measure
- Aggregation functions on individual objects inside a merged object (link coming soon)
I've encountered quite a few questions around this new feature, so I've started documenting in the SCN WIKI full details on how to use it and what you'll see (feedback most welcome!):
The main WIKI links to 3 child pages where I provide specific examples of the rules in action including:
- How to identify which formulas may be affected by calc engine changes
- How to manually correct the formulas without the tool (especially useful if you're upgrading to BI 4.1 but not yet to SP03)
- How to enable/disable the rewrite rules
- How to tell a rewrite has occurred via the WebI logs
The tool is also mentioned in the Release Notes for BI 4.1 Support Pack 03 and further detail can be found here in Developer's SCN Document on WebI Calc Changes (highly recommended for those upgrading to BI 4.1 from any version!):
Thanks!
