Q-7: What is an availability group in EWM?

Answer:

Availability Group


The availability group is an attribute of a stock type and represents a storage location linked to a warehouse.

For example, stock type F1 in warehouse W001 is assigned to availability group PL01/0001 and is used to manage unrestricted use stock in plant PL01 and storage location 0001.

You configure availability groups in Customizing for Extended Warehouse Management under Configure Availability Group for Put-away.

You assign availability groups to storage locations in Customizing for Extended Warehouse Management under Map Storage Locations from ERP System to EWM.

If the warehouse is linked to several storage locations, you can assign an availability group to the warehouse process type in Customizing for Extended Warehouse Management under Define Warehouse Process Type. The system uses this availability group in an inbound process to determine the stock type of the stock on the goods movement bin of the warehouse request. Without this setting, the system determines the stock type from the availability group linked to the storage location of the delivery item from Logistics Execution.

Stock types in EWM and Plant/Storage location in ERP are linked via availability groups.

First we need to define availability group for warehouse

Q-8: Which Stock Type Role are present in EWM?

Answer:

Normal/Unrestricted Stock, Blocked Stock, Quality Stock, Return Stock, Scrapping Stock etc.


Q-9: What is the link between Stock Types and Storage Types?

We can assign an availability group to the storage type and based on that whenever a Warehouse Task (WT) is confirmed for the Storage Type stock type will change.

If the mandatory option is checked, its means whenever stock is moved from other availability groups, the stock transfer will happen automatically in back ground

1.     Storage Type: 0010 (High Rack Storage Type)

Q-10: What is an owner in EWM how it can use in EWM?

Answer:

An owner is a business partner that represents the party of the organization that owns the stock.

It is useful during the consignment process, when order from an external vendor, then goods will remain the property of the external vendor, and later on, we can do the posting change to move stock from vendor to own valued stock.

Q-11: What is the party entitled to dispose of and how is it useful in EWM?

Answer:

Party entitled to dispose is a business partner that represents the party that is entitled to dispose of the warehouse stock. Usually, it is business partner of the plant in which the stock is placed.

During delivery processing, party entitled to dispose comes from the ERP plant which is assign to the delivery number.

If warehouse assigned to multiple plants, stock can be differentiated based on party entitled to dispose and warehouse product master data can also be maintained separately for each plant.

Q-12: How is Batch Management activated in EWM?

Answer:

First we need to activated Batch management in ERP system as well. Batch data is centrally managed, and Classes/Characteristics can be distributed to the EWM system through CIF.

To use batch management in EWM, batch management needs to be activated at the material level.

When EWM creates or changes batches, it attempts to call the ERP system synchronously to inform it about the change. If you use the default update control (blank), then the system triggers an error message if there is an error in the call (for example, if the ERP system is temporarily offline or the batch is locked). For update control values 1 and 2, EWM won’t display a direct error message and will attempt to update the batch asynchronously later. This lets you continue to work in EWM without interruption.

Q-13: What are some ERP characteristics available for batches as stock attributes in EWM?

Answer:

LOBM_HERKL (COO)

LOBM_VFDAT (SLED and minimum shelf life)

LOBM_ZUSTD (Batch Status)
