"There are no primary or candidate keys in the referenced table 'dbo.Table01' that match the referencing column list in the foreign key 'FK_Table01_Table02'."
Although the column list in the first table DO MATCH the column list in the second table with the same data types...
After alot of investigations, my collegue and I discovered it has to do with the order of columns being referrenced... Never thought that this matters... but this solved the issue... :)))
