Diagnosis
The node NODEID = [] is a leaf and an interval node. The node nameNODENAME = '&V3&' of the leaf lies within the value range [LEAFFROM -LEAFTO] = [&V4&] of the interval node. This is not allowed because theleaf and the interval node are child nodes of the same parent nodeNODEID = &V2&.
Note that a maximum of 50 characters is available for message variables.For this reason the node name NODENAME = '&V3' or the value range[LEAFFROM - LEAFTO] = [&V4&] might not be displayed correctly.

Procedure
Try to localize the problem. If the hierarchy is loaded from an SAPsource system, you can check whether the extracted data is correct byexecuting transaction RSA3 in the source system. If necessary, check ifthe data is modified with a user exit. If the hierarchy is loaded from afile, check the contents of this file. The problem might also be due toan error in the transfer rules or in the transformation.
You can identify the two duplicate nodes from the values for the node IDNODEID = [&V1&].
The problem can be caused by identical nodes delivered more than oncefrom the source. It is also possible that incorrect values forparameters such as the node name NODENAME or validity period [DATEFROM,DATETO] are the cause of the problem.
First check if the values for the node name NODENAME = '&V3&' and forthe value range of the interval node {LEAFFROM - LEAFTO] = [&V4&] arecorrect. The node name and the interval boundaries of the value rangeconsist of the characteristic value for the hierarchy basiccharacteristic and the characteristic values of all the characteristicscompounded to this characteristic. Errors creating the node name or theinterval boundaries often result in duplicate nodes.
If the structure of the hierarchy is defined as time-dependent, the timevalidity of a node can be restricted with the fields DATEFROM andDATETO. Duplicate nodes generally do not occur if the validity intervalsof two nodes do not overlap in time. In this case check if the fieldsDATEFROM and DATETO are filled.
