Average cost is used for valuing inventories. There is an average cost update program that is run every 3 minutes. At times there have been significant changes to the cost (100 times or more) for the material and we are unable to find the source or logic for such changes and how the same has been calculated.
Is there any document on how the program works and is there an audit trail of entries passed by the average cost update to understand the source and logic of such entries.
Thanks in advance
