Prevent pricing errors or omissions in the final bid. Ensure quick and effective validation before sending to the customer. Desired operation: When generating or sending a quote, the system detects the materials at 0. A warning window appears, indicating the items concerned. The user can then: Correct the quantities, or confirm that he wants to continue regardless. This feature would help improve the quality of submissions and reduce the risk of human error.
