We have had an ongoing problem though all the RMS versions with inter-store transfers not completing from the sending store to the receiving store.
The tell-tale symptom is the sending store will send it through the HQ client and will show up in the PurchaseOrder and PurchaseOrderEntry tables, but the receiving store never gets the transfer, so their corresponding entries never show up in the PurchaseOrder tables.
I think that the cause of this problem happens when the sending store gets delayed while uploading the HQ Client, so by the time the transfers gets into HQ, the receiving store has already synchronized for that time period, and that transfer gets missed.
I have tried updating the sending store's PurchaseOrder entry with LastUpdated and CreationDate, and scheduling a 401 worksheet for the receiving store to go back and update for that time period again, but to no avail.
Does anyone know what the trigger in HQ is to pass the transfer on to the receiving store? My only solution right now is to put the transfer back in the sending store, remove all trace of the original transfer, and recreate the whole thing - tedious.
