Cannot create rotating assets

Body

Today you decided that would create several assets with associated rotating items!

But it seems that "something" is conspiring against you!

When you try to associate an asset to a rotating item that has a classification, you get the following error message:

BMXAA4187E - The relationship ASSETSPEC does not exist for business object ITEMSPEC.Verify that the relationship specified in the parameter ASSETSPEC exists in the Maxrelationship table

Then you look at the message and think:
"You again! This message that is often generic and does not really represent the problem"

Don't worry.... please read the procedure bellow:

4.) Find for ROTATINGASSETSPEC Relationship and make sure the Where Clause field is filled as follows:

5) Click in New Row and complete the fields as follows:                 
Relationship = ASSETSPEC                                                
Child Object = ASSETSPEC                                                
Where Clause = (assetspec.inheritedfromitem = 'yes' and assetspec.classstructureid = itemspec.classstructureid and assetspec.assetattrid = itemspec.assetattrid)
