Hi Jonathan, i would do it like this: - add in your global model tables named attributs, attributs_value and values, - any table (let's call it XTable) that will eventually has need extra column per client will be linked to attributs_value via a table XTable_Attributs (For maximum flexibility). Hope that helps, Best regards
