Helo Gurus,

 

       I have 3 tables namely , Table1 , Table2 and Table3.  Table1 is inner joined with Table 2 and Table 3. Using table visual , Now am trying to drag the columnA from  Table2 and ColumnA from Table3 (Note : Table 2 & Table 3 are not connected directly but joined with Table1). Am getting the below error.

Kindly post your suggestion on this error / how to avoid this.

    Anonymous as error suggested, you cannot use columns from not related table, you need to use common table which is related to these two tables

    You can select the relationship columns yourself.  I do it all the time.  for example, i make a date relationship to get certain tables to join, or if you have an order ID or user ID in both  tables you just match up the like columns from the two tables.  If you have multiple tables to join, you have to adjust the settings to do 1 to many or many to many
