Wave
Definition
Grouping of warehouse request itemsto control warehouse activities, for example, picking, or posting changes.
These groupings are then processed together in subsequent processes, for example, the transfer of all warehouse request items assigned to a wave at a certain point in time to warehouse task creation. The warehouse tasks created are then forwarded to warehouse order creation.
Use
Extended Warehouse Management (EWM) can combine warehouse request items and split items into waves on the basis of criteria such as activity area, route, or product.
Waves can be created automatically or manually with the use of existing
wave templates
. If you want to manually create a wave, on the
SAP Easy Access
screen, choose

Example
Grouping Warehouse Request Items
The following graphic shows how EWM combines items from different warehouse requests with different routes and picking areas into waves. EWM combines the items WR Item 10 and WR Item 20 from warehouse request 100 and the item WR Item 10 from warehouse request 20 to form wave 1 on the basis of route A.
Assignment of an Item to Different Waves
The following graphic shows how EWM assigns a warehouse request item with different partial quantities to different waves if the rough picking location determination process yields different items due to a quantity-dependent picking strategy.
In rough picking location determination, EWM assigns warehouse request item 10 with a quantity of 111 of product A to three different picking areas in accordance with the quantity-dependent picking strategy. One piece is assigned to picking area PA1, ten pieces are assigned to picking area PA2, and 100 pieces are assigned to picking area PA3.
