When using SAS^® High-Performance Markdown Optimization, online optimization might fail when a GEO/PROD has an actual price of 0 (zero). This failure is shown in the HiPerfMerchIntelGridSvr.log

[Thread-53] DEBUG - 20111222:15.38.22.30: Error: job 'Aggr' encountered a fatal error

Additionally, it is likely that multiple data quality errors will be logged as well (for the same ThreadID):
