We use the 'reverse engineer from database' feature to create an initial mapping. But then we usually have to do manual changes like map some pks, add flattened relationships, etc. If then the database schema needs to be changed we usually have a problem as 'reverse engineer from database' overwrites everything. There seems to be the possibility to replace only selected tables but if you do this the relationships are messed up. Is there a way to merge the changes with the current model/mapping? thanks Tobias ___________________________________________________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
