Warehouse Management

Absolute efficiency

PSIpenta Warehouse Management supplements the inventory management system. It manages and controls the processes and sub-areas within a storage location. All storage locations apart from the goods receipt warehouse and the shipping warehouse can also be managed with sub-areas. All area-specific stock movements are logged in the stock journal and can thus be traced.

Storage locations and stock location sub-areas

The storage locations themselves are defined in the basic data and are plant-specific. Storage locations managed with sub-areas consist of at least one buffer area and one or more storage locations. For each stock receipt or issue to or from storage locations managed with sub-areas, a stock transfer is created for stock location management. This stock transfer is processed further according to the configured automation level. Within the storage locations, the stock location sub-areas are defined and combined into sub-area groups. Sub-area groups can be combined according to size, load capacity or hazard class, for example. They thus allow different types of storage compartments within a high-bay warehouse system to be managed. Free sub-areas are managed and items awaiting stock receipt are assigned accordingly. Batches are taken into account in this process. Stock location sub-areas can automatically be assigned to zones indicating the accessibility of a stock location sub-area (zone 1: easily accessible, to zone 3: difficult to access).

Selection of the stock location sub-area

Stock receipt can be performed according to various principles:

  • Manual storage of several articles in one area
  • Assignment of free stock location sub-areas selected from a list
  • Article-dependent distribution to multiple stock location sub-areas
  • Consideration of occupied stock location sub-areas during new stock receipt
  • Fixed item area when using automatic storage

Stock issues are always batch-specific and are also performed according to the principles of manual assignment or list selection and FIFO (first-in-first-out). The selection and assignment processes for stock management can be automated. If the location is selected automatically, the assignment is performed according to item. However, different items can be placed in one location manually.

Stock movements

For each stock receipt or issue to or from storage locations managed with sub-areas, a stock transfer is created that is processed by the stock location management. The course of a stock receipt, transfer or issue is tracked and controlled through the stock transfer. As a result of posting to a storage location managed with sub-areas, stock receipts and issues are initially assigned to buffer areas. Feedback from the stock transfers causes the corresponding quantities to be posted from the buffer location to the designated stock location or vice versa.

Stock receipts and issues can be processed together in one operation. Stock receipt and issuing operations can be summarised according to different criteria.

Inventory count

The inventory count for storage locations managed with sub-areas is available in parallel to the item inventory:

  • Item inventory for storage locations not managed with sub-areas
  • Space inventory for storage locations managed with sub-areas

When using a sub-area related inventory selection, it is specified for which stock location sub-areas or stock location stocks of a storage location the inventory is to be created. The lines selected are combined under one inventory count number to form an inventory count list. A physical record of actual stock is generated using an inventory count list. Once the location inventory count has been posted successfully, all the results of the inventory count and the added differences in quantity between the posted stock and the stock identified in the inventory count can be recorded in a closing report (inventory count proof) as an inventory count proof for each sub-area.
