Customizing the Length of the ‘asStoredChildName’ Column
When saving (uploading) parts or library objects with long names to the Windchill server, Windchill Workgroup Manager can generate values for the asStoredChildName attributes on an EPMMemberLink that exceed the default maximum character length of two hundred (200). This causes the save (upload) action to fail with the following (Oracle DB) error message .
ORA-12899: value too large for column "<server>"."EPMMEMBERLINK"."ASSTOREDCHILDNAME" 
(actual: 229, maximum: 200)
Therefore, it is recommended to increase the maximum allowable length of the asStoredChildName attribute for the wt.epm.structure.EPMDependencyLink class.
