Choose the Sphere

Use the navigation buttons or the Page Up or Down keys to go to the Sphere for which you want to define a recursive relationship. Move to the relationship definition page and make sure that the two specified spheres are the same. Define the desired relation values, bearing in mind that flow finding can be performed either for one and only one relation value or for all relation values. If you wish to use the recursive relationship for other possible meanings as well as the "Triggers" relation, these should be confined to cross level needs or other relationships which cannot conflict with the flow relationship. It is, however, allowable to use multiple equivalent values of the "Triggers" relation to distinguish, for example between "Must follow", "May follow" and "Is one of a set of possible Followers".

Required Relations

A flow can be defined as any relationship in which one sphere item necessarily or conditionally follows another. It is a special case of the standard recursive relationship. Decide which sphere(s) are appropriate. For example:

After performing Process A, perform Process B

or

After performing Process A, perform Process B or Process C.

Thus, if the defined relation value used is "Triggers", the necessary relations to be entered are:

The second case may be further defined by setting the probabilities of taking one or other action. There is no limit on the number of branches which may be defined for exit from a given process.
