OLE DB or ODBC Error - Column doesnt exist or doesnt have relationship

[TylerVono]

Hello, Is anyone familiar with this error who can help? I have a simple equation:

DateDiffMOQ = DATEDIFF('MOQ Log'[Start Date],'MOQ Log'[End Date],month) - *Compares two dates, counts the months between and calculates a $ total over each month*.  Simply, my 'MOQ Log' table just needs to link to my 'Date Table' and my 'Demand Seg Anchor' table.

My Error:

I do not want to link table: 'MOQ Log' with the table 'Demand Seg'. However I need to refresh 'Demand Seg' with another table called 'Demand Seg Anchor' but it stops me altogether from doing so.

How can I refresh the Demand Seg Table as well as make sure the MOQ Log[DateDiffMOQ] can be found?

Any suggestions?
