| ERROR | (XSDPART17) workspace object contains a leaf (workspace object) that is not part of the partition dimension workspace object. |
| CAUSE | In the definition of a CONCAT partition template, one of the partitions was dimensioned by a dimension that is concat-related to a partition dimension, meaning it shares some leaves with the partition dimension, but it contained some leaves that are not in the partition dimension. |
| ACTION | Either modify the dimensionality of the partition template to include a concat dimension that contains all the desired leaves, or pick a different dimension for the partition. |
