I got business logic error

This error does not appear before I upgraded. Is there any idea guys? I new to Epicor. please explain in detail please.

I mean, as far as Epicor errors go, that one is pretty cut-and-dry.
Find those two fields and populate them with data. They should be named similar to what the error message says.

I cannot find these two that the issue.

Both of the fields have a “_c”, so they’re custom. Who’s the person that created them? I’d start there.
Otherwise, you’ll need to turn on field help and click through the fields until you can find them.

Or, if they’re not truly required, go into the Extended Properties screen, pull them up, and remove the Required checkbox.

Yeah, I found the fields in data dictionary but I cannot find that in the Customer Maintenance. I will keep looking for them. Thank you
