Lots of times when there is nothing seems to be wrong, the error ‘Item is not on inventory’ pops up when posting transfer orders for receiving the items. This i have been facing for number of customers lately. What usually causes this problem and what is the solution especially when items are already shipped and ready to recieve.
I have seen most of the times reservation and off-late adjustments (i.e. from 5.0) from In-Transit as one of the factor. But as I said “most of the times”. I would suggest to search here people wud have for sure shared there experiences. [:D]
