Special care is required when settings up document types for inter-warehouse transfers. Inter-warehouse transfers between the main office and branch offices should affect the stock of both warehouses.

There are two types of transfers.

Uncontrolled Transfer

With uncontrolled transfer, the stock transfer document (transfer slip) is always created by the issuing warehouse.

Document type set-up:

This type of transfer has two issues:

1. The receiving warehouse has no control over the goods that are transferred to it. Upon synchronization, only a transfer slip is sent to the receiving location, without any documents that would confirm that the transferred goods have acutally been received, or received in the correct quantity.
2. The receiving warehouse will record the transferred stock only after synchronization. If negative stock is not allowed, the location will not be able to issue the transferred items until a synchronization has been performed.

Controlled Transfer

The controlled transfer alleviates the shortcomings of the uncontrolled transfer, but adds complexitiy. Instead of transfer slips, internal issue and receiving slips are used.

Document type set-up:

The issuing warehouse creates an internal issue slip, the receiving warehouse an internal receiving slip. The records are immediately affected in both warehouses. Finding errors is relatively simple: compare issue and receiving slips to check if anything is missing.

With the internal issue slip, prices must be filled in from the current warehouse. These prices must then be entered to the internal receiving slip in order to achieve correct valuation at the receiving warehouse.
