Diagnosis
No contingents were found that exist in the lifetimes of the two objectsto be linked.

System Response
To be able to assign the object to a contingent, the contingent periodmust be within the objects validity period. This was not the case forany of the contingents, and the object therefore could not be assignedto a contingent.

Procedure
When you create objects for an operation/exercise, select the validityperiod of the object so that the contingent to be assigned is withinthis period, or select a relationship target that has contingentassignments within the required object validity period.
When assigning existing objects, select a relationship target withcontingent assignments that are within the validity periods of theseobjects.
