Assume we choose the base price origin for calculating the gross profit as the item cost. After posting hundreds of invoices, we realized that our item cost was incorrect, and should be adjusted. Let's say we adjust the item cost by a landed cost document or by Inventory Revaluation. Is there any way we can somehow go back to the posted invoices and automatically adjust or recalculate the gross profit based on the new item cost? I know I can manually open every invoice and adjust the base price one by one, but to do that for hundreds of invoices would be very tedious.
