Justification for not going negative with costing method Ave

kapil4dynamics

Hi,

Can somebody give me an example what harm can be caused when we get into negative quantity with costing method average and continue with posting ?

and same what harm it can do(with an example) if i post less than 0 quantity from purchase order or sales order again with costing method average ?

Or in other words a very well explained GIGO costing method

Question is for 4.0 version

<Edit> I wanted some example, as i know this if u have some -ve quantity posted (except transfer shipment ) with any cost the valuation report and the G/L will be in -ve. The posting of receipts and invoice should be chronological and allow posting from and posting to also plays a big role. I told all this to my client but i am asked to give some more explanation, what example can i give to the client for this to prove the mess.
