In the case of a partially posted order, there are a lot more places you should check besides the OE history:
* Did open AR get updated? (AROPNFIL table)
* Did your inventory get decremented? (IMINVTRX, IMINVLOC, and if there were bin/lot/serial items, IMLSMST, IMINVBIN, IMLSTRX and IMBINTRX)
* Did the proper debits and credits to A/R, Sales, COGS and Inventory take place in the ARDISFIL and IMDISFIL tables?
I would also reset allocations and run the Load OE View Master file utilities. You should also check every order in that day's billing comparing the physical invoices to the Macola data. Make sure what is left in open orders is correct (normally just whatever was backordered).
As to why this happened, typically it would be a lost network connection or the machine that ran the post was shut down or crashed in the middle of the post.
