No need to popup anything on the server.This is exactly the point: If you do not want the error message of 4D, you must check the unique value BEFORE you save the record - means, you must programmatically disable this automatic feature. Makes no sense...>How about making SKU unique, and if you don't want to make it unigue, >don't call it SKU...In this case I believe WebCat has to do a lookup - which you can also do with few lines of code, and for any fieldname you want. Second, you often want to search for two fields, which have to be unique if they are both in one record - user AND password for example. Here one single reserved fieldname is not enough... No, the feature was worth to think about, but the possible solutions go straight against WebCat's flexibility which I like most (beside the speed).
