How to resolve/root cause an ambiguity error in relationships

[Syndicate_Admin]

So, I seem to understand this all the time. I try to make an active relationship and receive an error that says, in part:

"A direct active relationship between [Table 1] and [Table 2] cannot be entrusted because that would introduce ambiguity between [Table 3] and [Table 1]"

For example.

So, is there an approach to root causing this and getting to the exact problem to address/fix?

Thank you

Hi @Syndicate_Admin ,

Based on your description, the issue you may have faced is getting error on creating relationship between 2 tables and when this new relationship makes a circular path in the model. It will realise an ambiguity in reaching to the third table because there are 2 paths, one directly and another via an intermediate table.

So I suggest that you may need to re-adjust the relationship between the three tables or create a new table as a bridge to connect these tables. It depends on how your model was created. Please refer to the link below, I think it is very clear.

Hope that's what you were looking for.
