Modify Column attributes in the Table Maintenance Generator

Hello,

Thanks for the response.  BRAND and PROGRAMID are already keys, but accept blank entries in SM30 for this table. 

I read some posts about the PBO events that I might be able to edit to adjust logic for various requirements with regards to validation.  I haven't worked that kind of validatin in the PBO event of a TMView before.  Do you know of a good tutorial/post regarding how to handle custom column validation in the PBO of the maint. screen.  CHecking google....

Thank you!
