Hi,
Are you using Reverse engineer to create a database model from an existing database? What’s your source database, SQL server or other third-party database?
The error “Relationship is not fully connected” indicates that there is a connection line missing which is related to the relationship between two databases or servers. If you are using Reverse Engineer in Visio 2010, the model is automatic generated and
we cannot view how the generation is processed from data to Visio. In this situation, maybe we need to compare the model with your source data one by one manually to fix the connection.
I notice it is a big data model, and it is difficult to find the connection one by one. I suggest we can ask a question in General Office Development forum to confirm if there is any related code can scan the big model for you to fix the connection:
