Not All Items are Aggregated

I remember seeing this error message, but cannot remember the context. Can you describe when you see this one?

Edit: You say when you open a part. Do you use custom Server Method on your Part? Sound like a Federation issue

This is happening whenever I open or save a Part (ItemType Part).  I accidently deleted the Part Document relationship, I'm wondering if that is where the error is coming from.  

Deleting the Document relationship sounds like a very possible source for this problem.

The Part/Document connection is used by many standard Aras components. I assume your Part-Changes tab throw the error. Depending on your Innovator versions, it´s already triggered when you open a part, even when you don´t click on the changes tab itself. The changes tab expects, that your Document relationship is still there.

I would not recommend to delete the relationship. If you don´t need it, better hide it.

Yeah, it was a mistake.  I was trying to clean things up and made the mistake.  I can't get into my back-up to get the ID for the relationships to rebuild it.

Using a backup would be the cleanest solution. Problem is, that this tab is hard to rebuild. You not only need to rebuild the Relationship, but in worst case also the included properties. All id´s and config´s id have to match the original. 

One solution: Host a test database with original Aras database and do lot of export/import or SQL magic. 

I ran logging on the server and noticed that the Method VC_GetFilesForViewingForItem is being called.  This Method calls the Method VC_GetItemsForAggregation.  My guess is that VC_GetItemsForAggregation calls a SQL script called GetItemsForAggregation.  I'm guessing that this script looks for the relationship between the Part and Document ItemTypes.  Since I deleted the relationship it was causing an error.  I created a new relationship between them & I am not receiving the error anymore.
