Oracle Error Message
ORA-36679: (XSDPART17) workspace object contains a leaf (workspace object) that is not part of the partition dimension workspace object.
Reason for the Error
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.
Solution
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.
