Diagnosis
You attempted to create an elementary transaction on the next level tothe elementary transaction you selected.
However, this is not possible in the following situations:

• The selected elementary transaction is a complex OTC option (transaction
form 062), a Bermuda option (transaction form 063), or a forwardvolatility agreement (transaction form 065) and there is already anelementary transaction on the next level.
In this case, you cannot create an additional elementary transaction onthe next level down from the elementary transaction.

• The elementary transaction you selected is the underlying of a Bermuda
option (transaction form 063)
In this case, you cannot create an additional elementary transaction onthe next level down from the underlying.

• For OTC options (transaction form 061), you can create additional
underlyings in the next level only if the options are basket options.
