Field help (SRGLOCDEF) 

In the case where the receipt transaction authorizes a dock receipt (parameter active in the transaction setup), a dock location field appears in the receipt note header. This makes it possible to enter a location of the 'dock' type which will then be transferred by default as the return location for all receipt note lines. The specified dock location must be associated with the warehouse, when the latter is specified.

SEEINFOA dock location corresponds to a location of the type "pending storage". This authorizes the entry of stocks whose characteristics of lot, sub-lot, and serial number are not necessarily immediately identified. This type of receipt is used to rapidly book the goods and to then later to more precisely identify them and put them away. This put-away process is performed in the functionPut-away plan.
