I can insert a single document against an existing wtPart, but need to add multiple in a single operation instead of inserting multiple documents and then linking against the wtPart.
How can I insert multiple documents of the same type against a existing wtPart? Is this possible within the software as is, or do I require customization? If this needs customization, any pointers on API's would be great.
Assuming the documents are already in Windchll, you can use the Copy/Paste action to add multiple documents to a wt.part. Just collect all the documents via Copy (to the Clipboard) and then Paste them all in one shot.
If the documents are not in Windchill, you can use the Multi-Doc Create action or simple drag-n-drop with Desktop Integration to create the new documents first.
You do have a good point, there is no Add Multi-Doc toolbar action in the Described By or Referenced By tables.
