Hi, I have problems with numbering. In a table the orders of each client are loaded, each client must have a correlative numbering, but when loading orders several users at the same time, the numbers are repeated and I can not find a way to solve it. Obviously each record has a unique id, and there are no problems of data overlap, but neither can correlation be maintained. Even sometimes repeated numbers are already made several orders ago. I gather that this is because they have not updated the app and the last number that loaded from that device remained as the last number. I can not find a way to solve it. Can someone help me?
