Can not create relationship between Tables (not many to many)

[vipe110]

Hi guys,

I seems to run into a fairly simple problem but somehow I can not figure it out.

I need to create a relationship from 2 tables. The common column is SKU_Number (as image)

The relation is just one to one but everytime I add SKU_Number from one table and unit price from the other, it can not map a relationship. The unit price from the other table return error.

Please help me with this.

Thank you.
