@ThereseLogeais I will try that, I think that may be the solution. Don't print the alias in the work table but create a link using Item Code + Customer Number to the alias table, if there is a customer alias, it will print, if there is no customer alias, it will not print. I do think that will work.
@MarkKotyla , no I could not link to the alias table with a UDF
@DianeRuth & @KennyDaniel the customer alias absolutely DOES print, it's the general aliases when a customer alias does not exist that are the problem.
