Another Problem NAT 6.1.1 --> 6.3.9 regarding DDMs

Hello all!

We got another problem with our Natural for Solaris upgrade from 6.1.1 to 6.3.9.

We’re using a third party software to transport Natural-Programs, User-Messages and DDMs between our different environments. Everything is working good - except DDMs. The vendor of that software was not able to find the error. :x

So my question is: Does anyone know differences between 6.1.1 and 6.3.9 regarding DDMs? (Of course I searched the release notes…)
