FASTR BU Roll-ups

We are on A7.3 cum 8. When creating summary level FASTRs, I am having
problems getting business units to roll-up correctly and consistently. Some
business units work. Some don't. We've been unable to identify a cause or
pattern. Can anyone provide some guidance?

We were on cume 8 and I have a vague recollection of having to apply a PTF A73PC000PE because of multiple problems and I think this was one of them. I'm not sure how it fits into the Y2K stuff you likely also already applied so be careful. Sorry I can't help more.

We did have to load a FASTR fix after the Y2K issues. We are on 7.3 cum 9.
I believe it was a73000JS. The Y2K updates wiped out some mods they
released on fix a73000pe.
