Dynamic field creation in Attain 3.60

Hi All I’m trying to make a codeunit, which automatically creates som fields in the std. tables ( like table 18 aso. ). Normal fields I don’t have any problem with, but when I try to create Options I can’t set the optionstring, and the same problem with flowfields, I don’t know how to set the calcformulae. I have read that Navision has released the tools they’re using, and that it should be possible with these new variables/codeunits, but I can’t seem to find the right ones. Does anyone know how this can be done, if at all possible. Best regards Henrik
