Help With Relationships

I am thoroughly turning around in circles about this error.  How do I resolve this set of relationships?  I have a ton of other queries that run on the same format... and I don't understand why this one reports this:

How do I resolve this?

Hi  @jamiers ,

You can find the join relationships for all tables in Power BI, but Power BI doesn't have the tools to point out relationship issues directly at the moment.

Generally speaking, if there is an error in a table-to-table connection, you can determine the general direction of the error from the error message and identify the problem step by step through the regular table-to-table connection troubleshooting checklist.

You can submit an idea for it at Home (microsoft.com) and wait for users with the same needs as you to vote for you to help make it happen as soon as possible.

Thanks for the reply from @amitchandak , please allow me to provide another insight: 
Hi  @jamiers ,

Based on the error message display, you can check the following:

The wrong active relationship is set. Generally, there can be only one active relationship between two tables. If there is more than one relationship, you need to set it as inactive.

Use the Manage relationships dialog box to set a relationship as active or inactive, or set the active relationship in the Edit relationship dialog box.

Specific screening instructions may also lead to errors. Therefore, you can refer to the specific official documentation below for information about the relationship modeling and activity relationships between constructed dimension tables and fact tables.

 specific screening directions may also cause errors.

Do the relationships in the table form a closed loop of Table A -> Table B - > Table C -> Table A. You can create a bridged table to act as an intermediate table, and the rest of the tables are connected to the bridged table.

So I have some pretty complex relationships going on.  Is there a tool that might be able to point me to where the issue might be?  I have already run down my list of relationships and clearly I am missing whatever the issue is.

@jamiers , seems like there are loops or multiple paths between tables. This can be because of bi-directional joins. Make that there are two joined  table A and B, you do not have to path to reach from A to B
