Compiling with DDM files

I have a logical file on System B called awdevicel2.
On System A, I created a DDM over awdevicel2 on system B also called awdevicel2.

In my RPG program on system A, I have my F spec defined as follows (pardon any formatting errors):
Fawdevicel2if e k disk

When I compile I get the RNF2120 external description not found error. I have done a wrkobj and verified that the object
exists, that the authority is okay, and that it's in my library list.

What did I miss?

TIA
