I'm trying to establish a data model between the two tables in the WB attached. The 'Game ID' 1st column has has all unique dates on that table and I wanted to use that column as the primary key column on that WS. The 'Game ID" column on the Pitching WS would be the foreign key on that sheet. When I try to establish the relationship the dialogue does not see the two worksheets so I can't initiate the relationship. Can you help me out?

Hi JPK1066,


The problem here is that the table in your Pitching worksheet spans every possible cell in the worksheet, meaning it has over 16,000 columns. The Relationships dialog isn't capable of handling this many columns, which is why you weren't able to create the relationship.


I have recreated the Pitching table so that it only spans the width and height of the data within it, and was then able to create a relationship as shown in Expert Skills Lesson 6-2 Create a simple data model.

For more on creating Tables, see the video lesson: Expert Skills Lesson 1-11 Convert a range into a table and add a total row.


I have attached a copy of your workbook with the table resized and the relationship added:
