problem creating module pool

I'm trying to create dialog program ( probably referred to as a module pool in today's terminology) in R/3 4.7 and I'm getting authorization errors when I use the naming convention I have always used SAP + M + Z + program name. For example if my program name was TEST the dialog program name would be SAPMZTEST. In creating this program I answer yes to creating the top include, then yes to the proposed name of the top include which is MZTESTTOP. Then I get stopped by the authorization error.

My question is this: Is there a new way to create dialog programs in 4.7 or is this merely an authorization problem - if so, what value needs to be the object entry of S_DEVELOP

I would greatly appreciate some guidance on this

Thanks,

Brent
