Diagnosis
An account or root account which is to be placed in the hierarchy isalready present in another hierarchy. The two hierarchies overlap withrespect to time. (Every account within a relation type may only becontained in one and only one hierarchy for each day)
If a hierarchy is created using a copy of another hierarchy, everyaccount underneath the root account of the source hierarchy is checkedto see whether it can be copied to the new hierarchy. If the accountis contained in another hierarchy and the two overlap time-wise, thenthis error message is generated.
