The Teamcenter preference, "SEEC_Enable_MultipleRevisions" is enabled. When opening an assembly with multiple revisions a SEEC error occurs;
"Cannot open file because at least one document has links to two different revisions of the same Item. Each document can use only one revision of an Item. Change your revision rule and retry the operation."
With the preference "SEEC_Enable_MultipleRevisions" enabled assemblies that use multiple revisions of an item can be opened with the following caveats:
The assembly has more than one level.
Each subassembly contains only one item revision.
There are no patterned components.
Precise BOM View Revisions are used.
