Unable to create relationship.

[bhavsar08]

Dear Experts, i have two tables, one column contains unique id's and from another table one column contains unique + duplicate values and i wanted to create a relationship "one to many" as for one to many but I am not able to create one. i am getting error the cardinality you selected isn't valid for this relationship. i tried every possible outcome but had hard luck.

Hello Experts, 

the issue is resolved, i had smartsheet connected to PBIX and the issue was i wanted one to many relationship but in my first column there was text mentioned, and that caused the table not to convert to numbers, so i removed those and applied one to many relationships. so even i have duplicates in second column now i am able to create relationship.
Thanks All!

Cheers!

Hi @bhavsar08 ,

The error is often caused with the relationship you are trying to create from a column in the "FROM" table to a column in the "TO" table. One of the columns must have unique product numbers. You need to make sure that one of the tables has a unique product number and then you won't have any issue.

@bhavsar08 , You can blank value on one side in the key column or duplicate value.

Blank and null is also not allowed check that
