RoI should post to the COGS account, not PC.  Check the DTR. 

(Sage 100 won't let you do a RoG for a Drop Ship PO).

All I see is a post to a COGS but this po is showing in the purchases clearing report?

Try the regular PC report, not the new one "From History".

OK, it is not on the regular PC report, so whats is the relevance of each one, is the history just to see what po's didnt not close out before period end?

Purchases Clearing is a "now" report.  A highly requested feature was to be able to run the PC report "as of" a date in the past (i.e. the previous period end)... for reconciliation purposes. 

Since the From History report is new, it might not be 100% perfect.  If you find a data pattern that shows on the new "history" report incorrectly, report it to Sage for potential correction.
