Ordering Customized Cume package

I am having difficulty with Management Central when ordering PTF from IBM.
The central system is at V5R3 and the system I want to order the latest CUME
for is at V5R2.  I have connected to Management Central using OPS NAV and
collected the inventory successfully.

When I am at IBM's web site and input the central system all is ok.  After
selecting the system to create the Customized CUME for, it fails "Unable to
collect inventory from Management Central."

I am at a loss and cannot find any errors in the logs I am looking at.
Where should I be looking?  Central system or remote system?
