Issue:
Several Miscellaneous Receipt transactions for item FABP-10422 were processed with a Unit Cost of 0.00000, as shown in "Review Item Costs" (Review Transaction Costs):

• Doc 5133181 — Qty 33 — Unit Cost 0
• Doc 5133180 — Qty 178 — Unit Cost 0
• Doc 4779324 — Qty 5 — Unit Cost 0
• Doc 4780189 — Qty 1 — Unit Cost 0
• Doc 4780185 — Qty 1 — Unit Cost 0

Questions:

1. If a new Misc Receipt with the correct Unit Cost is submitted now, will the Cost Processor recalculate/overwrite the average cost of the previously costed (0-cost) transactions, or does it only apply going forward from the new transaction's timestamp?
