Problem Note 58850: Holdout Forecast Accuracy scenarios might fail in a multi-captain environment
 |  |  |  |  |
SAS® Revenue Optimization Holdout Forecast Analysis might fail for some scenarios when running in a grid environment with multiple captains where all captains share access to the data mart via NFS. The MerchIntelGridSvr.log file might contain the following error:

This error occurs when Holdout Forecast Accuracy is requested for several model groups in different partitions and those partitions are distributed across multiple captains.
The workaround for this issue is to ensure that all model groups included in a Holdout Forecast Accuracy request reside on the same captain. The simplest way to guarantee that all model groups are on a single captain is to ensure that all model groups in the request are in a single partition.
