What’s the difference between the forecast in the weekly overview and Forecast analysis report?

The Forecast Analysis report shows two different types of Forecast Sales value. For current weeks, the report shows 'Latest Forecast', instead of 'Actual' and 'Locked Forecast', however the report only shows 'Locked Forecast' and 'Actual' for past weeks.  

The 'Locked Forecast' reflects the Forecast Sales value at the point of Approval, and the 'Latest Forecast' reflects the Forecast Sales value, as it is at that moment in time. Due to the nature in which customers can use the system, Forecast Sales can be changed during the week to allow managers to react to changing environments and update the system accordingly. This is the reason why the system shows a 'Latest Forecast' value. This is the same value that would be shown as 'Forecast' within the Analysis Report and the Sales Forecast screen in LP.

The Weekly Overview Report shows 'Forecast Sales', which should reflect the same as the 'Latest Forecast' value in the Forecast Analysis report.
