How do create a directional M:N relation

Old Versions
#1

Hi,

I want to implement dependencies of processes. I tried to use a domain with an n:n relation.

I can only insert "process A needs process B".  Creating "process B needs process A" can not created.

This is like a graph database, I need a directional N:N domain. Looks the N:N domain is now implemented with no directional information.  

Tried to implement it as an class, don't work.

Any sugestions?

Thanks.

if you have defined a domain on the same class, the direction is given by the descriptions “Direct description” and “Inverse description”.
For example if your domain is dependence between CI, with “Direct description” = ‘serves CIs’ and “Inverse description”=’ is served by CIs’, then for each CI adding a relationship in TAB Relations you will find in the domain list both ‘it serves CIs’ and ‘is served by CI’ and you can choose the right direction.
