Diagnosis
No suitable operation contingents could be found for the higher-levelforce element.This can be due to several reasons:
The higher-level force element is not an operation, nor does it have anyrelationships to an operation.
The higher-level force element is an operation, but all the contingentsof this operation are in the past, which means that newsrelationships cannot be created for these contingents.
The higher-level force element has operational relationships, but theseare all in the past, which means that new relationships cannotbe created with reference to this contingent.

System Response
Since operational relationships must always have a reference tocontingents or operational relationships of the higher-level forceelement, no operational relationship can be created in this casebetween the two force elements selected.
