To view Assemblies information in AVEVA NET the user needs to add some extra Breakdown Node configurations to the AVEVA NET Portal. The example shown will extend the Default Asset Breakdown node, but the same principle can be used on any user defined Breakdown Node’s.
If you used the default AVEVA classifications as shown in Default System Classification of Items, you will have the items classified thus:
PIPE+Pipeline
…
ASWL+Assembly
ASMBLY+Assembly
BLOCK+Block
HSTIFF+Hstiff
HPANBO+Hpanbo
HPANEL+Hpanel
HPLATE+Hplate
…
Otherwise+Component
