I clicked "customer classification file" in the "transaction management" of UFIDA software, and a prompt popped up saying: customers have no classification, how can this be solved ~

Double-click System Management-after the screen appears, click Register-after the screen appears, enter the identity and password of the A/C supervisor, and select the A/C number and year to be modified-after the screen appears, click A/C-after the screen appears, select Modify-and then click Next (about 3-4 times) until you find an interface with customer classification settings, and click. Then you can do what you want.
