Combing graphs from 2 datasets on the same tab
But I am not trying to do a calculation I am trying to have filters work for 3 different data sets. I do not see how this resolves my issue.
Is it possible for you to share the sample data file or snapshot of the relationship view?

Not sure if this will help. So I have 3 data sets on one page. I have two them working, the third one it will not let me create another many to many relationship. So my Jobs and Utilization tables are working and joined to the calendar table and the company and yard table. This enable both to filter correctly. My budget and revenue table it will not let me join to the company, yard or calendar table. As you can see I have added another calendar table but it is only letting me make one join there. Does this help?

The general consensus is to avoid many-to-many relationships where possible (it can wreak havoc in calculations...)
Can you not create lookup/dim tables as bridge tables between the different fact tables by linking common fields (and removing duplicate values to enable one-to many relationships)?
If you can provide sample fact tables with dummy data/values I will happily give it a tryI created a 2 bridge tables, my company and yard tables, that are many to one with just the company and yards listed in the bridge tables, but I need to link 3 tables to them and it will not let me do more than 2. When I try to make the relationship active I get this error. And what makes no sense to me is that the Yardname table and the Calendar table are not linked at all in any way. There is no way to link them.

BTW, looking at the screenshot of your model, I think you are confused about how relationships, lookup tables, and filter conexts work. Just as an example, it is VERY rare to have more than one relationship between two tables (generally you only need more than one relationship between two tables if for example your fact table has two date fields - for example, purchase date and delivery date).
And it seems you have two or three stemming from one table to another in a few tables.
So I cleaned everything up and now it is letting me make the joins and everything is working as it should on my combined tab. Which is great. I have one last issue that is not working as expected. I have my Invoice Created date and I have linked that in a many to one relationship with the date field in my calendar table. It is active. I have made the Year and Month columns has my slicers on my tab, but whenever I select them all of my data goes blank. I went and reformatted the date so that it was no longer date time just the date, I have removed the link and added it back but nothing is working. I really am at a loss.
