will dds alias keyword cause level checks?

I want to start adding alias names with nice, long, clearly understandable names. We are dabbling in DDL, but most of our stuff is DDS. But we are moving to SQL and exporting files as spreadsheets, so nice clear column names is a good thing.

I must add the alias in DDS because system I navigator only allows me to change the short name, which I do NOT want to change since that is what RPG uses.

I am afraid I will get level checks on my rpg programs if I use chgpf pointing to the new DDS with aliases.

Can anyone confirm or deny level checks before I jump in?

Thanks.
