Invalid definition of MetaAssociation

[rafgutierrezc90]

Hi, in the Entity (DM) class we are creating a tab with the following attributes "Owner" and "Custodian" wich is it a org unit in both cases. However, when we make all the modifications MEGA shows us an error: "Invalid definition of MetaAssociation, you need to connect a macro to this metaassociation". We created the metaassociation between Entity(DM) and OrgUnit. 

Thanks

Hello rafgutierrezc90

Data modeling metamodel has a specific implementation. It is necessary to follow a specific procedure to extend this metamodel

This is a known issue.

See this discussion in the forum http://community.mega.com/t5/HOPEX-Product-Forum/Error-when-creating-new-MetaAssociation-with-Class-...

More generally, do not hesitate to search for strings of error message in the knowledge base or forum.
