We have had several instances where a receiving clerk, while doing a MIGO goods receipt for a subcontract item will expand the subcontract components tree and either un-check the OK indicator or zero out the quantity of the component items. The result is that the top level item is received into stock without consuming any of the components. After this happens, the components can not be consumed into the Purchasing Document, resulting in errors in both our inventory of components at the vendor, and the moving average price of the received material.
If the mistake is recognized quickly, the goods receipt could be reversed and re-received correctly, but in most cases, it has not been discovered until long after the fact, and the received item itself has already been sold or consumed into a higher level assembly.
In addition to TRAINING, does anyone know of a way to prevent this problem ?
