Topic: Preventing from entering duplicate record
Hello everyone once again,
This time I have a real nightmare. I tried to finally start with my final project but there's a huge gap that needs to be filled. Since we have machines with unique serial numbers that contains numbers and letters, I want to prevent being duplicating while saving the record. But so far I couldn't achieve it.
I found numerous articles and samples and tried to customize the codes and scripts to my project but still nothing.
One that somehow worked is that Derek put on the Duplicate sample, until I close the project and reopen it and then idk something went wrong and it's not working again. It stores the serial number as 0 when serial number contains letters but with numeric is working fine.
I send a sample, any help really appreciated.
