PO Daily Receipt Registers posting VERY (!) slow

SOLVED

Sage 100c Advanced 2018 v6.00.10.0

When we update a Receipt of Good Register, even for just a small receipt, it can take 30 minutes or more to update.   No other updates in the system take as long


Is there a way to refresh the work/crystal files so as to clear this up?  If so, which files and what should I try?  I tried reinitializing some of the work files but no change.
Any other suggestions?

The process works, just slow as all get out and now starting to affect production.

Thanks
