Figure 6-18. Decomposition Tree
However, because of the large number of members that a dimension might contain, it can become a performance
drain on the system.
Each item listed in a vertical column of the decomposition tree is counted against this limit. Note that this limit
applies to only one column of items as highlighted in Figure 6-18 . The total number of items in all columns might well
exceed this value. This limit should not be set higher than is needed for the users to perform the analysis required.
Trusted Data Source Locations
PerformancePoint Services stores its metadata in SharePoint lists and libraries. These locations must be listed
as “trusted” before PPS will consider them valid locations from which to read its objects. By default, all locations
within SharePoint are automatically considered trusted, as Figure 6-19 shows.
